Abstract
This document defines the expression of Whois++ protocol (RFC1835) responses within MIME (Multipurpose Internet Mail Extensions) (RFC2046) media types. The intention of this document, in conjunction with RFC 2957 is to enable MIME-enabled mail software, and other systems using Internet media types, to carry out Whois++ transactions.

whoispp-response Syntax
The following grammar, which uses ABNF-like notation as defined in RFC2234, defines a subset of responses expected from a Whois++ server upon receipt of a valid Whois++ query. As such, it describes the expected structure of a whoispp-response media type object.
N.B.: As outlined in the ABNF definition, rule names and string literals are in the US-ASCII character set, and are case-insensitive.
