Abstract
摘要
This document defines the expression of Whois++ protocol (RFC 1835) queries within MIME (Multipurpose Internet Mail Extensions) (RFC 2046) media types. The intention of this document, in conjunction with RFC 2958 is to enable MIME-enabled mail software, and other systems using Internet media types, to carry out Whois++ transactions.

The following grammar, which uses BNF-like notation as defined in [RFC2234] defines the set of acceptable input to a Whois++ server. As such, it describes the expected structure of a whoispp-query media type object.
以下语法使用[RFC2234]中定义的类似BNF的表示法，定义了Whois++服务器的可接受输入集。因此，它描述了WHOISP查询媒体类型对象的预期结构。
N.B.: As outlined in the ABNF definition, rule names and string literals are in the US-ASCII character set, and are case-insensitive.
注意：如ABNF定义中所述，规则名称和字符串文字在US-ASCII字符集中，不区分大小写。
