IESG Statement on the Usage of Assignable Codepoints, Addresses and Names in Specification Examples
Date: 24 May 2010
Protocol specifications and other documents intended for RFC publication often include useful examples with correctly formatted and syntactically
valid codepoints, addresses or names. Examples of codepoints, etc, are
such as email addresses, domain names, IP addresses or ports. Codepoint
values may already have been assigned or may become assigned in the
future to entities on the Internet.
