To repeat the nice definition that Keith gave us, and which most
of us seem to like:

"The sender believes this message will be irrelevant 
after the indicated date/time."

- hence we could call it "Relevant-until:"


The problem that I see with using a different name at this
point is that "Expires" already exists, with roughly the
meaning that we want - not only in the netnews context,
but also for MIXER (RFC 2156), as a renamed version
of the obsolete "Expiry-Date" field according to RFC 4021.
Additionally, despite being obsolete, Expiry-Date is
currently in use, in the way that we want, with MS Outlook.

So, when we weigh the pro's against the con's, is it worth
changing the name to "Relevant-until"? I'm not sure...
