IBTD. No documented standard with strange variations in syntax in
practice is worse than a clear standard with MUSTs and MUST NOTs.
Morons intentionally violating MUSTard are no compelling reason to
"undocument" Expires:. And this header field exists in the Mixer
and Netnews RFCs, an attempt to "undocument" the idea is futile.
I think we are at the point where a fresh draft would be helpful.
