HTML Format for RFCs
RFCs的HTML格式
Abstract
摘要
In order to meet the evolving needs of the Internet community, the canonical format for RFCs is changing from a plain-text, ASCII-only format to an XML format that will, in turn, be rendered into several publication formats. This document defines the HTML format that will be rendered for an RFC or Internet-Draft.
为了满足互联网社区不断发展的需求，RFC的标准格式正在从纯文本、仅ASCII格式转变为XML格式，而XML格式又将被转换为多种出版物格式。本文档定义了将为RFC或Internet草稿呈现的HTML格式。

As described in [RFC7990], the RFC Series is changing. One of those changes includes the RFC Editor publishing a non-canonical HTML version of RFCs.
如[RFC7990]所述，RFC系列正在发生变化。其中一个更改包括RFC编辑器发布RFC的非规范HTML版本。
This document describes the HTML format that will be used as one of the publication formats for the RFC Series. It defines a strict subset of HTML appropriate for RFC Series documents. The visual layout of the document will be defined through a cascading style sheet (CSS) [W3C.REC-CSS2-20110607]. The CSS will be included in the HTML file but will be described in [RFC7993].
本文档描述了将用作RFC系列出版物格式之一的HTML格式。它定义了适用于RFC系列文档的严格HTML子集。文档的视觉布局将通过层叠样式表（CSS）[W3C.REC-CSS2-20110607]定义。CSS将包含在HTML文件中，但将在[RFC7993]中描述。
The details (particularly any vocabularies) described in this document are expected to change based on experience gained in implementing the new publication toolsets. Revised documents will be published capturing those changes as the toolsets are completed. Other implementers must not expect those changes to remain backwards compatible with the details described in this document.
本文档中描述的详细信息（尤其是词汇表）预计将根据在实施新发布工具集过程中获得的经验进行更改。修订后的文档将在工具集完成后发布，以捕获这些更改。其他实施者不得期望这些更改与本文档中描述的细节保持向后兼容。
This section lists the design requirements used to create the HTML format described in this document. These requirements build on those found in [RFC6949]. Many of these requirements are naturally fulfilled by using the output of the preparation tool [RFC7998].
本节列出了用于创建本文档中描述的HTML格式的设计要求。这些要求以[RFC6949]中的要求为基础。通过使用准备工具[RFC7998]的输出，这些要求中的许多自然得到了满足。
o The HTML has to render correctly on a list of browser versions that the RFC Editor will keep up to date outside of this document.
o HTML必须在RFC编辑器将在此文档之外保持最新的浏览器版本列表上正确呈现。
o The format will consist of a subset of HTML deemed to be widely implemented by common browsers at the time the specification is created, likely to continue to be widely implemented, and unlikely to cause security issues. This will maximize the chances that future HTML renderers (such as new web browsers) will continue to produce readable text from the HTML format without the format needing to be changed frequently.
o 该格式将由HTML的子集组成，这些HTML在创建规范时被认为是由普通浏览器广泛实现的，可能会继续被广泛实现，并且不太可能导致安全问题。这将最大限度地提高未来HTML呈现器（如新的web浏览器）继续从HTML格式生成可读文本的可能性，而无需频繁更改格式。
o These requirements are expected to change in the future to reflect the expectation that HTML rendering will be required for current versions of browsers and platforms, while ideally continuing to render correctly on recent versions of those browsers.
o 这些要求预计将在未来发生变化，以反映当前版本的浏览器和平台将需要HTML呈现的预期，同时理想情况下继续在这些浏览器的最新版本上正确呈现。
o The HTML documents from the RFC Editor or Internet-Drafts directory may be re-rendered from the canonical XML format in the future to ensure the ongoing readability of the documents. The intent is that any re-rendering would be due to exceptional circumstances rather than for minor annoyances.
o 将来，RFC编辑器或Internet草稿目录中的HTML文档可能会从规范XML格式重新呈现，以确保文档的持续可读性。其目的是，任何重新渲染都是由于特殊情况，而不是因为小麻烦。
o The HTML must display adequately in at least one text-based browser. Some consumers of the RFC Series can only access the documents on text-based terminals.
o HTML必须至少在一个基于文本的浏览器中充分显示。RFC系列的某些使用者只能在基于文本的终端上访问文档。
o The HTML document will be self-contained, without requiring external files for images, CSS, JavaScript, or the like. This will allow the HTML file to be moved over various non-HTTP transports (such as email, FTP, and rsync) without breakage.
o HTML文档将是自包含的，不需要图像、CSS、JavaScript等外部文件。这将允许HTML文件在各种非HTTP传输（如电子邮件、FTP和rsync）上移动而不会中断。
o JavaScript will be supported on a limited basis. It will not be permitted to overwrite or change any text present in the rendered HTML. It may, on a limited basis, add additional text that provides post-publication metadata or pointers if warranted. All such text will be clearly marked as additional.
o JavaScript将在有限的基础上得到支持。不允许覆盖或更改呈现HTML中的任何文本。它可能会在有限的基础上添加额外的文本，以提供发布后元数据或指针（如有必要）。所有此类文本将明确标记为附加文本。
o The HTML document will allow easy local override of the default CSS formatting. This will allow users who have a different visual style that they prefer to make RFCs display with that style without having to alter the contents of the HTML document. This
o HTML文档将允许轻松地本地覆盖默认CSS格式。这将允许具有不同视觉样式的用户使用该样式显示RFC，而无需更改HTML文档的内容。这
might also be valuable for allowing people with specific accessibility needs to use a customized CSS.
对于允许具有特定可访问性需求的人使用定制的CSS来说，这可能也是很有价值的。
o HTML tags in documents will rarely have attributes whose only purpose is to affect the rendered styling, and those will only be used if it would not be possible to specify that styling in a CSS. No such attributes are known at this time.
o 文档中的HTML标记很少具有仅用于影响呈现样式的属性，并且只有在无法在CSS中指定该样式时才会使用这些属性。目前尚不知道此类属性。
o Both user-defined and auto-generated anchors must be supported and linkable, with user-defined anchors appearing in an "id" attribute. Auto-generated anchors will be generated for every heading, paragraph, and so on, not just those that do not have user-defined anchors. User-defined anchors may, and auto-generated anchors will, appear next to paragraphs, figures, tables, blockquotes, and section titles.
o 用户定义的锚和自动生成的锚都必须受支持并可链接，用户定义的锚显示在“id”属性中。将为每个标题、段落等生成自动生成的锚定，而不仅仅是那些没有用户定义锚定的锚定。用户定义的锚定可能会出现在段落、图表、表格、块引号和章节标题旁边，自动生成的锚定也会出现在段落、图表、表格、块引号和章节标题旁边。
o All sections, subsections, figures, and paragraphs should have stable numbered link anchors. Additionally, anchors expressed in the source XML should be exposed as anchors in the HTML output as well.
o 所有章节、小节、图和段落应具有稳定的编号链接锚。此外，源XML中表示的锚也应该在HTML输出中作为锚公开。
o The HTML must make it easy to separate sections along with all of their subsections into separate files. This will make creating EPUB documents easier in the future.
o HTML必须能够轻松地将部分及其所有子部分分离到单独的文件中。这将使将来创建EPUB文档变得更容易。
o The HTML produced for Internet-Drafts will differ from that produced by the RFC Editor due to differences in the output from the prep tool.
o 由于prep工具的输出不同，为Internet草稿生成的HTML将不同于RFC编辑器生成的HTML。
o The abstract must be marked up or tagged in a way that popular search engines will extract it as a summary.
o 摘要必须以流行搜索引擎将其提取为摘要的方式进行标记或标记。
o Normative information must be easily accessible to the following consumers:
o 规范性信息必须便于以下消费者获取：
* People with impaired vision, including those that use large fonts and those that use screen readers
* 视力受损的人，包括使用大字体的人和使用屏幕阅读器的人
* People with difficulty distinguishing between colors
* 难以区分颜色的人
* People who use devices with small screens, such as cell phones
* 使用小屏幕设备的人，如手机
o Specific instances where goals for accessibility are important in the design choices of the format have been called out in the text.
o 文中列举了可访问性目标在格式设计选择中很重要的具体实例。
o Note: designing for these consumers does not preclude the use of features they cannot use, but it does require that key semantic data not be lost when read using the tools and settings that are required by a given constituency.
o 注意：为这些消费者设计并不排除使用他们无法使用的功能，但它确实要求在使用给定选区所需的工具和设置读取时，关键语义数据不会丢失。
The RFC Editor will periodically determine which version of the HTML specification will be referenced for tools generating the format defined in this document. The starting version will be that defined in [W3C.REC-html5-20141028], commonly known as "HTML5". Although the HTML specification mandates several of the syntax and structure rules described in this document, they are called out here for emphasis.
RFC编辑器将定期确定生成本文档中定义的格式的工具将引用哪个版本的HTML规范。起始版本将是[W3C.REC-html5-20141028]中定义的版本，通常称为“html5”。尽管HTML规范规定了本文档中描述的几种语法和结构规则，但此处将它们作为重点。
The processor emitting HTML from the XML source will follow these rules:
从XML源发出HTML的处理器将遵循以下规则：
o The HTML output is encoded as UTF-8, as specified in [RFC3629].
o HTML输出编码为UTF-8，如[RFC3629]所述。
o The document is valid HTML.
o 该文档是有效的HTML。
o Double quotes (U+0022 QUOTATION MARK: ") are used to quote attribute values unless the HTML specification forbids quoting a particular attribute.
o 双引号（U+0022引号：）用于引用属性值，除非HTML规范禁止引用特定属性。
o Each logical line is terminated solely with a \n (U+000A: LINE FEED), otherwise known as "Unix-style" line endings.
o 每个逻辑行仅以一个\n（U+000A：换行符）终止，否则称为“Unix样式”行结束符。
o Code points below (U+0020: SPACE) or character entity references that generate them (e.g. 	), other than (U+000A: LINE FEED) may not be used. Note: this rule explicitly forbids \t (U+0009: CHARACTER TABULATION), \f (U+000C: FORM FEED), and \r (U+000D: CARRIAGE RETURN) from appearing in the HTML output.
o 除了（U+000A：换行符）之外，不能使用下面的代码点（U+0020：空格）或生成它们的字符实体引用（例如	；）。注意：此规则明确禁止\t（U+0009:字符制表）、\f（U+000C:表单提要）和\r（U+000D:回车符）出现在HTML输出中。
o Comments in the source XML, if any, will not be copied into the HTML.
o 源XML中的注释（如果有）将不会复制到HTML中。
o The HTML output will be pretty-printed, using whatever consistent rules are deemed best by the developers of the HTML production tools.
o HTML输出将被打印出来，使用HTML生产工具的开发人员认为最好的一致性规则。
Note: none of these rules affect the rendered output of the HTML, but they are intended to increase the chance that text comparison tools (e.g., "diff") that operate on the HTML output are easier to write.
注意：这些规则都不会影响HTML的呈现输出，但它们旨在增加操作HTML输出的文本比较工具（例如，“diff”）更容易编写的可能性。
This section lists items that are common across multiple parts of the HTML document.
本节列出HTML文档多个部分中常见的项目。
HTML elements that are generated from XML elements that include an "anchor" attribute will use the value of the "anchor" attribute as the value of the "id" attribute of the corresponding HTML element. The prep tool produces XML with "anchor" attributes in all elements that need them. Some HTML constructs (such as <section>) will use multiple instances of these identifiers.
从包含“anchor”属性的XML元素生成的HTML元素将使用“anchor”属性的值作为相应HTML元素的“id”属性的值。prep工具在所有需要它们的元素中生成具有“锚定”属性的XML。一些HTML构造（如<section>）将使用这些标识符的多个实例。
Each paragraph, artwork, or sourcecode segment outside of a <figure> or <table> element will be appended with a space and a "pilcrow" (U+00B6: PILCROW SIGN), otherwise known as a "paragraph sign". For the purposes of clarity in ASCII renderings of this document, in this document pilcrows are rendered as "¶". The pilcrow will be linked to the "id" attribute on the XML entity to which it is associated using an <a> element of class "pilcrow". For example:
<figure>或<table>元素外部的每个段落、艺术品或源代码段将附加一个空格和一个“pilcrow”（U+00B6:pilcrow符号），也称为“段落符号”。为清晰起见，在本文件的ASCII呈现中，pilcrow呈现为“¶；”。pilcrow将使用类“pilcrow”的<a>元素链接到与其关联的XML实体上的“id”属性。例如：
<p id="s-1.1-1">
Some paragraph text. <a class="pilcrow" href="#s-1.1-1">¶</a>
</p>
<p id="s-1.1-1">
Some paragraph text. <a class="pilcrow" href="#s-1.1-1">¶</a>
</p>
The pilcrow will normally be invisible unless the element it is attached to is moused over. The pilcrow will be surrounded by a link that points to the element it is attached to.
皮尔克罗通常是不可见的，除非它所连接的元素被鼠标移到上面。pilcrow将被一个指向它所附着的元素的链接包围。
Pilcrows are never included inside a <table> or <figure> element, since the figure number or table number serves as an adequate link target.
Pilcrow从不包含在<table>或<figure>元素中，因为图号或表号作为适当的链接目标。
Elements that might otherwise contain a pilcrow do not get marked with a pilcrow if they contain one or more child elements that are marked with a pilcrow. For example:
如果可能包含pilcrow的元素包含一个或多个子元素并用pilcrow标记，则不会用pilcrow标记这些元素。例如：
<blockquote id="s-1.2-1">
<p id="s-1.2-2">Four score and seven years ago our fathers brought
forth on this continent, a new nation, conceived in Liberty, and
dedicated to the proposition that all men are created equal.
<a href="#s-1.2-2" class="pilcrow">¶</a></p>
<!-- NO pilcrow here -->
</blockquote>
<blockquote id="s-1.2-1">
<p id="s-1.2-2">Four score and seven years ago our fathers brought
forth on this continent, a new nation, conceived in Liberty, and
dedicated to the proposition that all men are created equal.
<a href="#s-1.2-2" class="pilcrow">¶</a></p>
<!-- NO pilcrow here -->
</blockquote>
The front matter of the HTML format contains processing information, metadata of various types, and styling information that applies to the document as a whole. This section describes HTML that is not necessarily a direct transform from the XML format. For more details on each of the tags that generate content in this section, see Section 9.
HTML格式的前端包含处理信息、各种类型的元数据以及应用于整个文档的样式信息。本节描述的HTML不一定是XML格式的直接转换。有关本节中生成内容的每个标记的更多详细信息，请参阅第9节。
The DOCTYPE of the document is "html", which declares that the document is compliant with HTML5. The document will start with exactly this string:
文档的DOCTYPE是“html”，它声明文档符合HTML5。文档将以以下字符串开头：
<!DOCTYPE html>
<!DOCTYPE html>
The root element of the document is <html>. This element includes a "lang" attribute, whose value is a language tag, as discussed in [RFC5646], that describes the natural language of the document. The language tag to be included is "en". The class of the <html> element will be copied verbatim from the XML <rfc> element's <front> element's <seriesInfo> element's "name" attributes (separated by spaces; see Section 2.47.3 of [RFC7991]), allowing CSS to style RFCs and Internet-Drafts differently from one another (if needed):
文档的根元素是<html>。该元素包括一个“lang”属性，其值是一个语言标记，如[RFC5646]中所述，描述文档的自然语言。要包含的语言标签为“en”。<html>元素的类将从XML<rfc>元素的<front>元素的<seriesInfo>元素的“name”属性（用空格分隔；请参见[RFC7991]的第2.47.3节）逐字复制，允许CSS以不同的方式设置rfc和Internet草稿的样式（如果需要）：
<html lang="en" class="RFC">
<html lang="en" class="RFC">
The root <html> will contain a <head> element that contains the following elements, as needed.
根<html>将包含一个<head>元素，该元素根据需要包含以下元素。
In order to be correctly processed by browsers that load the HTML using a mechanism that does not provide a valid content-type or charset (such as from a local file system using a "file:" URL), the HTML <head> element contains a <meta> element, whose "charset" attribute value is "utf-8":
为了让浏览器能够正确地处理使用不提供有效内容类型或字符集的机制（例如从使用“文件：”URL的本地文件系统）加载HTML的HTML，HTML<head>元素包含一个<meta>元素，其“字符集”属性值为“utf-8”：
<meta charset="utf-8">
<meta charset="utf-8">
The contents of the <title> element from the XML source will be placed inside an HTML <title> element in the header.
XML源中<title>元素的内容将放在标题中的HTML<title>元素中。
The following <meta> elements will be included:
将包括以下<meta>元素：
o author - one each for the each of the "fullname"s and "asciiFullname"s of all of the <author>s from the <front> of the XML source
o author-XML源的<front>中所有<author>的“fullname”和“asciiFullname”各一个
o description - the <abstract> from the XML source
o description-来自XML源的<abstract>
o generator - the name and version number of the software used to create the HTML
o 生成器-用于创建HTML的软件的名称和版本号
o keywords - comma-separated <keyword>s from the XML source
o 关键字-从XML源中以逗号分隔的<keyword>s
For example:
例如：
<meta name="author" content="Joe Hildebrand">
<meta name="author" content="JOE HILDEBRAND">
<meta name="author" content="Heather Flanagan">
<meta name="description" content="This document defines...">
<meta name="generator" content="xmljade v0.2.4">
<meta name="keywords" content="html,css,rfc">
<meta name="author" content="Joe Hildebrand">
<meta name="author" content="JOE HILDEBRAND">
<meta name="author" content="Heather Flanagan">
<meta name="description" content="This document defines...">
<meta name="generator" content="xmljade v0.2.4">
<meta name="keywords" content="html,css,rfc">
Note: the HTML <meta> tag does not contain a closing slash.
注意：HTML<meta>标记不包含结束斜杠。
The <head> element contains a <link> tag, with "rel" attribute of "alternate", "type" attribute of "application/rfc+xml", and "href" attribute pointing to the prepared XML source that was used to generate this document.
<head>元素包含一个<link>标记，其中“rel”属性为“alternate”，“type”属性为“application/rfc+xml”，而“href”属性指向用于生成此文档的准备好的xml源。
<link rel="alternate" type="application/rfc+xml" href="source.xml">
<link rel="alternate" type="application/rfc+xml" href="source.xml">
The <head> element contains a <link> tag, with "rel" attribute of "license" and "href" attribute pointing to the an appropriate copyright license for the document.
<head>元素包含一个<link>标记，其中“rel”属性为“license”，而“href”属性指向文档的相应版权许可证。
<link rel="license"
href="https://trustee.ietf.org/trust-legal-provisions.html">
<link rel="license"
href="https://trustee.ietf.org/trust-legal-provisions.html">
The <head> element contains an embedded CSS in a <style> element. The styles in the style sheet are to be set consistently between documents by the RFC Editor, according to the best practices of the day.
<head>元素在<style>元素中包含嵌入式CSS。RFC编辑器将根据当时的最佳实践，在文档之间一致地设置样式表中的样式。
To ensure consistent formatting, individual style attributes should not be used in the main portion of the document.
为确保格式一致，文档的主要部分不应使用单个样式属性。
Different readers of a specification will desire different formatting when reading the HTML versions of RFCs. To facilitate this, the <head> element also includes a <link> to a style sheet in the same directory as the HTML file, named "rfc-local.css". Any formatting in the linked style sheet will override the formatting in the included style sheet. For example:
在阅读RFC的HTML版本时，规范的不同读者需要不同的格式。为了方便起见，<head>元素还包括一个<link>，指向与HTML文件位于同一目录中的样式表，名为“rfc local.css”。链接样式表中的任何格式都将替代包含的样式表中的格式。例如：
<style>
body {}
...
</style>
<link rel="stylesheet" type="text/css" href="rfc-local.css">
<style>
body {}
...
</style>
<link rel="stylesheet" type="text/css" href="rfc-local.css">
Each <link> element from the XML source is copied into the HTML header. Note: the HTML <link> element does not include a closing slash.
XML源中的每个<link>元素都被复制到HTML头中。注意：HTML<link>元素不包含结束斜杠。
In order to simplify printing by HTML renderers that implement [W3C.WD-css3-page-20130314], a hidden HTML <table> tag of class "ears" is added at the beginning of the HTML <body> tag, containing HTML <thead> and <tfoot> tags, each of which contains an HTML <tr> tag, which contains three HTML <td> tags with class "left", "center", and "right", respectively.
为了简化实现[W3C.WD-css3-page-20130314]的HTML呈现器的打印，在HTML<body>标记的开头添加了一个隐藏的HTML<table>类“ears”标记，其中包含HTML<thead>和<tfoot>标记，每个标记都包含一个HTML<tr>标记，其中包含三个带有类“left”、“center”和“right”的HTML<td>标记，分别地
The <thead> corresponds to the top of the page, the <tfoot> to the bottom. The string "[Page]" can be used as a placeholder for the page number. In practice, this must always be in the <tfoot>'s right <td>, and no control of the formatting of the page number is implied.
<thead>对应于页面的顶部，<tfoot>对应于页面的底部。字符串“[Page]”可用作页码的占位符。实际上，这必须始终位于<tfoot>的右侧<td>，并且不意味着控制页码的格式。
<table class="ears">
<thead>
<tr>
<td class="left">Internet-Draft</td>
<td class="center">HTML RFC</td>
<td class="right">March 2016</td>
</tr>

<tfoot>
<tr>
<td class="left">Hildebrand</td>

Information about the document as a whole will appear as the first child of the HTML <body> element, embedded in an HTML <dl> element with id="identifiers". The defined terms in the definition list are "Workgroup:", "Series:", "Status:", "Published:", and "Author:" or "Authors:" (as appropriate). For example:
关于文档整体的信息将作为HTML<body>元素的第一个子元素出现，嵌入到带有id=“identifiers”的HTML<dl>元素中。定义列表中定义的术语为“工作组：”、“系列：”、“状态：”、“已发布：”、“作者：”、“作者：”（视情况而定）。例如：

The table of contents will follow the boilerplate if the XML's <rfc> element's "tocInclude" attribute has the value "true". An HTML <h2> heading containing the text "Table of Contents" will be followed by a <nav> element that contains a <ul> element for each depth of the section hierarchy. Each section will be represented by a <li> element containing links by the section number (from the "pn" attribute) and by the name (from the "slugifiedName" attribute of the <name> child element). Each <nav>, <ul>, and <li> element will have the class "toc".
如果XML的<rfc>元素的“tocclude”属性的值为“true”，则目录将遵循样板文件。包含文本“目录”的HTML<h2>标题后面将跟随一个<nav>元素，该元素包含一个<ul>元素，用于节层次结构的每个深度。每个节将由一个<li>元素表示，该元素包含节号（来自“pn”属性）和名称（来自<name>子元素的“slugifiedName”属性）的链接。每个<nav>、<ul>和<li>元素都将具有类“toc”。
For example:
例如：
<h2 id="toc">Table of Contents</h2> <nav class="toc"> <ul class="toc"> <li class="toc"> <a href="s-1">1</a>. <a href="n-introduction">Introduction</a> </li> <ul class="toc"> <li class="toc"> <a href="s-1.1">1.1</a>. <a href="n-sub-intro">Sub Intro</a> </li> ...
目录<a href=“n-introduction”>简介</a></li><ul class=“toc”><li class=“toc”><a href=“s-1.1”>1.1</a><a href=“n-sub-intro”>sub-intro</a></li>。。。
The main body of the HTML document is processed according to the rules in Section 9.
HTML文档的主体根据第9节中的规则进行处理。
The back matter of the HTML document includes an index (if generated), information about the authors, and further information about the document itself.
HTML文档的背景内容包括索引（如果生成）、关于作者的信息以及关于文档本身的进一步信息。
The index will be produced as dictated by the RFC Editor's Style Guide [RFC-STYLE] if and only if the XML document's <rfc> element has an "indexInclude" attribute with the value "true" and there is one or more <iref> elements in the document.
当且仅当XML文档的<RFC>元素具有值为“true”的“indexInclude”属性且文档中有一个或多个<iref>元素时，才会按照RFC编辑器的样式指南[RFC-Style]的指示生成索引。
The index section will start with an <h2> heading containing the text "Index", followed by links to each of the lettered portions of the index. Links are not generated for letters that do not occur as the first letter of an index item.
索引部分将以包含文本“index”的<h2>标题开始，然后是指向索引每个字母部分的链接。不会为不作为索引项的第一个字母出现的字母生成链接。
For example:
例如：
<h2>Index</h2> <div class="index"> <div class="indexIndex"> <a href="#rfc.index.C">C</a> <a href="#rfc.index.P">P</a> </div> ...
<h2>索引</h2><div class=“Index”><div class=“indexIndex”><a href=“#rfc.Index.C”>C</a><a href=“#rfc.Index.P”>P</a><。。。
The index letter is followed by a <ul> tag that contains an <li> tag for each first letter represented in the index. This <li> tag has the class "indexChar" and contains an <a> tag with the id pointed to by the index letter as well as an "href" attribute to itself. The <li> tag also includes a <ul> tag that will contain the index items.
索引字母后面是一个<ul>标记，该标记包含索引中表示的每个第一个字母的<li>标记。此<li>标记具有类“indexChar”，并包含一个<a>标记，该标记的id由索引字母指向，并且其本身具有一个“href”属性。<li>标记还包括一个<ul>标记，该标记将包含索引项。
For example:
例如：
<ul> <li class="indexChar"> <a href="#rfc.index.C" id="rfc.index.C">C</a> <ul> <!-- items go here --> </ul> </li> ...
<ul><li class=“indexChar”><a href=“#rfc.index.C”id=“rfc.index.C”>C</a><ul><！--物品放在这里--></ul></li>。。。
Each index item can have multiple <iref> elements to point to, all with the same item attribute. Each index item is represented by an <li> tag of class "indexItem" containing a <span> of class "irefItem" for the item text and one of class "irefRefs" for the generated references (if there is at least one reference to the item not having a subitem). Each generated reference contains an <a> tag containing the section number where the <iref> is found, with an "href" attribute pointing to the "irefid" attribute of the <iref> element from the XML document. If the primary attribute of the <iref> element has the value "true", the <a> element in the HTML document will have the class "indexPrimary". Commas may be used to separate the generated references.
每个索引项都可以指向多个<iref>元素，所有元素都具有相同的项属性。每个索引项由类“indexItem”的<li>标记表示，该标记包含项文本的类“irefItem”的<span>，以及生成的引用的类“irefRefs”的一个（如果至少有一个引用项没有子项）。每个生成的引用都包含一个<a>标记，其中包含找到<iref>的节号，带有一个“href”属性，指向XML文档中<iref>元素的“irefid”属性。如果<iref>元素的主属性的值为“true”，则HTML文档中的<a>元素将具有类“indexPrimary”。逗号可用于分隔生成的引用。
For example:
例如：
<li class="indexItem"> <span class="irefItem">Bullets</span> <span class="irefRefs"> <a class="indexPrimary" href="#s-Bullets-1">2</a>, <a href="#s-Bullets-2">2</a> </span> <!-- subitems go here --> </li> ...
<li class=“indexItem”><span class=“irefItem”>项目符号</span><span class=“irefRefs”><a class=“indexPrimary”href=“#s-bollets-1”>2</a>，<a href=“#s-bollets-2”>2</a><span><子项位于此处--></li>。。。
If an index item has at least one subitem, the <li> of that item will contain a <ul>, with one <li> for each subitem, of class "indexSubItem". The format for each subitem is similar to that used for items, except the class of the first <span> tag is "irefSubItem".
如果索引项至少有一个子项，则该项的<li>将包含一个<ul>，每个子项有一个<li>，属于“indexSubItem”类。每个子项的格式与用于项的格式类似，但第一个<span>标记的类为“irefSubItem”。
For example:
例如：
<ul> <li class="indexSubItem"> <span class="irefSubItem">Ordered</span> <span class="irefRefs"> <a href="#s-Bullets-Ordered-1">2</a> </span> </li> </ul> ...
<ul><li class=“indexSubItem”><span class=“irefSubItem”>订购</span><span class=“irefRefs”><a href=“#s-Bullets-Ordered-1”>2</a></span>/li></ul。。。
At the end of the document, author information will be included inside an HTML <section> element whose "id" attribute is "author-addresses". The class names of the constituent HTML tags have been chosen to match the class names in [HCARD].
在文档末尾，作者信息将包含在一个HTML<section>元素中，该元素的“id”属性是“author addresses”。已选择组成HTML标记的类名，以匹配[HCARD]中的类名。
The information for each author will be separated by an HTML <hr> element with class "addr".
每个作者的信息将由类为“addr”的HTML<hr>元素分隔。

A few bits of metadata about the document that are less important to most readers are included after the author information. These are gathered together into a <div> of class "docInfo".
在作者信息之后，会包含一些对大多数读者不太重要的文档元数据。这些被收集到一个类“docInfo”的<div>。
The finalized time is copied from the <rfc> element's "prepTime" attribute. The rendered time is the time that this HTML was generated.

This section describes how each of the XML elements from [RFC7991] is rendered to HTML. Many of the descriptions have examples to clarify how elements will be rendered.
本节介绍如何将[RFC7991]中的每个XML元素呈现为HTML。许多描述都有示例来说明如何呈现元素。
The abstract is rendered in a similar fashion to a <section> with anchor="abstract" and <name>Abstract</name>, but without a section number.
摘要的呈现方式与使用anchor=“abstract”和<name>abstract</name>的<section>类似，但没有节号。

This element is used in the Authors' Addresses section. It is rendered as an HTML <address> tag of class "vcard". If none of the descendant XML elements has an "ascii" attribute, the <address> HTML tag includes the HTML rendering of each of the descendant XML elements. Otherwise, the <address> HTML tag includes an HTML <div> tag of class "ascii" (containing the HTML rendering of the ASCII variants of each of the descendant XML elements), an HTML <div> tag of class "alternative-contact", (containing the text "Alternate contact information:"), and an HTML <div> tag of class "non-ascii" (containing the HTML rendering of the non-ASCII variants of each of the descendant XML elements).
此元素用于“作者地址”部分。它被呈现为类“vcard”的HTML<address>标记。如果没有任何子代XML元素具有“ascii”属性，则<address>HTML标记包含每个子代XML元素的HTML呈现。否则，<address>HTML标记包括类“ascii”的HTML<div>标记（包含每个后代XML元素的ascii变体的HTML呈现）、类“alternative contact”的HTML<div>标记（包含文本“alternative contact information:”）和类“non-ascii”的HTML<div>标记（包含每个子XML元素的非ASCII变体的HTML呈现）。
Note: the following example shows some ASCII equivalents that are the same as their nominal equivalents for clarity; normally, the ASCII equivalents would not be included for these cases.
注：以下示例显示了一些ASCII等价物，为清晰起见，这些等价物与其标称等价物相同；通常，这些情况下不包括ASCII等价物。

Artwork can consist of either inline text or SVG. If the artwork is not inside a <figure> element, a pilcrow (Section 5.2) is included. Inside a <figure> element, the figure title serves the purpose of the pilcrow. If the "align" attribute has the value "right", the CSS class "alignRight" will be added. If the "align" attribute has the value "center", the CSS class "alignCenter" will be added.
艺术品可以由内联文本或SVG组成。如果艺术品不在<figure>元素内，则包括一个pilcrow（第5.2节）。在<figure>元素中，figure标题用于pilcrow。如果“align”属性的值为“right”，则将添加CSS类“alignRight”。如果“align”属性的值为“center”，则会添加CSS类“alignCenter”。
Text artwork is rendered inside an HTML <pre> element, which is contained by a <div> element for consistency with SVG artwork. Note that CDATA blocks are not a part of HTML, so angle brackets and ampersands (i.e., <, >, and &) must be escaped as <, >, and &, respectively.
文本艺术品在HTML<pre>元素中呈现，该元素包含在<div>元素中，以与SVG艺术品保持一致。请注意，CDATA块不是HTML的一部分，因此尖括号和符号（即<、>、和&）必须作为<；，转义>；，及；，分别地
The <div> element will have CSS classes of "artwork", "art-text", and "art-" prepended to the value of the <artwork> element's "type" attribute, if it exists.
<div>元素将有CSS类“artwork”、“art text”和“art-”，在<artwork>元素的“type”属性（如果存在）的值之前。

SVG artwork will be included inline. The SVG is wrapped in a <div> element with CSS classes "artwork" and "art-svg".
SVG艺术作品将包含在内。SVG被包装在一个<div>元素中，其中包含CSS类“artwork”和“art SVG”。
If the SVG "artwork" element is a child of <figure> and the artwork is specified as align="right", an empty HTML <span> element is added directly after the <svg> element, in order to get right alignment to work correctly in HTML rendering engines that do not support the flex-box model.
如果SVG“artwork”元素是<figure>的子元素，并且artwork被指定为align=“right”，则将在<SVG>元素之后直接添加一个空的HTML<span>元素，以便获得正确的对齐，以便在不支持flex box模型的HTML渲染引擎中正常工作。
Note: the "alt" attribute of <artwork> is not currently used for SVG; instead, the <title> and <desc> tags are used in the SVG.
注意：<artwork>的“alt”属性当前未用于SVG；相反，SVG中使用了<title>和<desc>标记。
<div class="artwork art-svg" id="s-2-17">
<svg width="100" height="100" xmlns="http://www.w3.org/2000/svg">

stroke="green" stroke-width="4" fill="yellow" />
</svg>
<a href="#s-2-17" class="pilcrow">¶</a>

Other artwork will have a "src" attribute that uses the "data" URI scheme defined in [RFC2397]. Such artwork is rendered in an HTML <img> element. Note: the HTML <img> element does not have a closing slash.
其他艺术品将具有“src”属性，该属性使用[RFC2397]中定义的“数据”URI方案。这样的艺术品在HTML<img>元素中呈现。注意：HTML<img>元素没有结束斜杠。
Note: such images are not yet allowed in RFCs even though the format supports them. A limited set of "data:" mediatypes for artwork may be allowed in the future.
注意：RFC中尚不允许使用此类图像，即使格式支持它们。未来可能会允许使用一组有限的“数据：”艺术作品媒体类型。

The <author> element is used in several places in the output. Different rendering is used for each.
<author>元素在输出中的多个位置使用。对每个对象使用不同的渲染。
As seen in the Document Information at the beginning of the HTML, each document author is rendered as an HTML <div> tag of class "author".
如HTML开头的文档信息所示，每个文档作者都被呈现为类“author”的HTML<div>标记。
Inside the <div class="author"> HTML tag, the author's initials and surname (or the fullname, if it exists and the others do not) will be rendered in an HTML <div> tag of class "author-name". If the <author> contains "asciiInitials" and "asciiSurname" attributes, or contains as "asciiFullname" attribute, the author's name is rendered twice, with the first being the non-ASCII version, wrapped in an HTML <span> tag of class "non-ascii", followed by the ASCII version wrapped in an HTML <span> tag of class "ascii", wrapped in parentheses. If the <author> has a "role" attribute of "editor", the <div class="author-name"> will also contain the text ", " (comma, space), followed by an HTML <span> tag of class "editor", which contains the text "Ed.".
在<div class=“author”>HTML标记中，作者的姓名首字母和姓氏（或全名，如果存在，其他则不存在）将呈现在类“author name”的HTML<div>标记中。如果<author>包含“asciiInitials”和“asciiSurname”属性，或包含“asciiFullname”属性，则作者的姓名将呈现两次，第一次是非ASCII版本，包装在类“non-ASCII”的HTML<span>标记中，然后是包装在类“ASCII”的HTML<span>标记中的ASCII版本，包装在括号中。如果<author>具有“editor”的“role”属性，则<div class=“author name”>还将包含文本“，”（逗号，空格），后跟类“editor”的HTML<span>标记，其中包含文本“Ed.”。
If the <author> element contains an <organization> element, it is also rendered inside the <div class="author"> HTML tag.
如果<author>元素包含<organization>元素，那么它也会在<div class=“author”>HTML标记中呈现。
<div class="author">

As seen in the Authors' Addresses section, at the end of the HTML, each document author is rendered into an HTML <address> element with the CSS class "vcard".
正如在Authors'Addresses部分中所看到的，在HTML的末尾，每个文档作者都被呈现到一个带有CSS类“vcard”的HTML<address>元素中。
The HTML <address> element will contain an HTML <div> with CSS class
"nameRole". That div will contain an HTML <span> element with CSS
class "fn" containing the value of the "fullname" attribute of the
The HTML <address> element will contain an HTML <div> with CSS class
"nameRole". That div will contain an HTML <span> element with CSS
class "fn" containing the value of the "fullname" attribute of the
<author> XML element and an HTML <span> element with CSS class "role" containing the value of the "role" attribute of the <author> XML element (if there is a role). Parentheses will surround the <span class="role">, if it exists.
<author>XML元素和一个HTML<span>元素，其中CSS类“role”包含<author>XML元素的“role”属性值（如果有角色）。括号将围绕<span class=“role”>（如果存在）。
<address class="vcard"> <div class="nameRole"> <span class="fn">Joe Hildebrand</span> (<span class="role">editor</span>) </div> ...
乔·希尔德布兰德（Joe Hildebrand）编辑。。。
After the name, the <organization> and <address> child elements of the author are rendered inside the HTML <address> tag.
在名称之后，作者的<organization>和<address>子元素在HTML<address>标记中呈现。
When the <author> element, or any of its descendant elements, has any attribute that starts with "ascii", all of the author information is displayed twice. The first version is wrapped in an HTML <div> tag with class "ascii"; this version prefers the ASCII version of information, such as "asciiFullname", but falls back on the non-ASCII version if the ASCII version doesn't exist. The second version is wrapped in an HTML <div> tag with class "non-ascii"; this version prefers the non-ASCII version of information, such as "fullname", but falls back on the ASCII version if the non-ASCII version does not exist. Between these two HTML <div>s, a third <div> is inserted, with class "alternative-contact", containing the text "Alternate contact information:".
当<author>元素或其任何子元素具有以“ascii”开头的任何属性时，所有作者信息将显示两次。第一个版本被包装在一个HTML<div>标签中，标签的类为“ascii”；此版本更喜欢ASCII版本的信息，如“asciiFullname”，但如果ASCII版本不存在，则使用非ASCII版本。第二个版本被包装在一个HTML<div>标记中，该标记具有类“non-ascii”；此版本更喜欢非ASCII版本的信息，如“全名”，但如果不存在非ASCII版本，则使用ASCII版本。在这两个HTML<div>之间插入第三个<div>，类为“alternative contact”，包含文本“alternative contact information:”。

In the output generated from a reference element, author tags are rendered inside an HTML <span> element with CSS class "refAuthor". See Section 4.8.6.2 of [RFC7322] for guidance on how author names are to appear.
在引用元素生成的输出中，author标记在带有CSS类“refAuthor”的HTML<span>元素中呈现。有关如何显示作者姓名的指南，请参见[RFC7322]第4.8.6.2节。
<span class="refAuthor">Flanagan, H.</span> and
<span class="refAuthor">N. Brownlee</span>
<span class="refAuthor">Flanagan, H.</span> and
<span class="refAuthor">N. Brownlee</span>
If there is exactly one <references> child, render that child in a similar way to a <section>. If there are more than one <references> children, render as a <section> whose name is "References", containing a <section> for each <references> child.
如果只有一个子<references>，则以类似于<section>的方式渲染该子对象。如果有多个子<references>，则渲染为名为“references”的<section>，每个<references>子级包含一个<section>。
After any <references> sections, render each <section> child of <back> as an appendix.
在任何<references>部分之后，将<back>的每个<section>子部分作为附录呈现。

This element renders in a way similar to the HTML <blockquote> element. If there is a "cite" attribute, it is copied to the HTML "cite" attribute. If there is a "quoteFrom" attribute, it is placed inside a <cite> element at the end of the quote, with an <a> element surrounding it (if there is a "cite" attribute), linking to the cited URL.
此元素的呈现方式类似于HTML<blockquote>元素。如果存在“cite”属性，则会将其复制到HTML“cite”属性。如果有一个“quoteFrom”属性，它将被放置在quote末尾的<cite>元素中，并在其周围有一个<a>元素（如果有“cite”属性），链接到引用的URL。
If the <blockquote> does not contain another element that gets a pilcrow (Section 5.2), a pilcrow is added.
如果<blockquote>不包含另一个获取pilcrow的元素（第5.2节），则添加pilcrow。
Note that the "—" at the beginning of the <cite> element should be a proper emdash, which is difficult to show in the display of the current format.
请注意，<cite>元素开头的“&mdash；”应该是正确的emdash，这在当前格式的显示中很难显示。

This element is rendered as an HTML <a> tag with CSS class "relref" and "href" attribute of the "derivedLink" attribute of the element. Different values of the "displayFormat" attribute cause the text inside that HTML <a> tag to change and cause extra text to be generated. Some values of the "displayFormat" attribute also cause another HTML <a> tag to be rendered with CSS class "xref" and an "href" of "#" and the "target" attribute (modified by any applicable <displayreference> XML element) and text inside of the "target" attribute (modified by any applicable <displayreference> XML element). When used, this <a class='xref'> HTML tag is always surrounded by square brackets, for example, "[<a class='xref' href='#foo'>foo</a>]".
此元素呈现为HTML<a>标记，带有该元素“derivedLink”属性的CSS类“relref”和“href”属性。“displayFormat”属性的不同值会导致HTML<a>标记中的文本发生变化，并生成额外的文本。“displayFormat”属性的某些值还导致另一个HTML<a>标记被呈现为CSS类“xref”和“href”的“#”和“target”属性（由任何适用的<displayreference>XML元素修改）以及“target”属性内的文本（由任何适用的<displayreference>XML元素修改）。使用时，此<a class='xref'>HTML标记总是用方括号括起来，例如，“[<a class='xref'href='#foo'>foo</a>]”。
The output is an <a class='relref'> HTML tag, with contents of "Section " and the value of the "section" attribute. This is followed by the word "of" (surrounded by whitespace). This is followed by the <a class='xref'> HTML tag (surrounded by square brackets).
输出是一个<a class='relref'>HTML标记，内容为“Section”，值为“Section”属性。然后是单词“of”（被空格包围）。然后是<a class='xref'>HTML标记（用方括号括起来）。
