Re: Archaic HTTP "From:" Header

Register "webid" as a Link Relation Value and ese the LINK header as in
Link: <http://...." rel="webid">

This will make sure you don't step on someone else's header, no-one will
step our yours. This will also allow you to include it in the header and
(when appropriate) include it within a message body.
