I posted this back on 12/10/87, but received no response. Does anyone have an answer yet? A formal specification of the 'Supersedes' header has not yet appeared. Can anyone give me an "official" spec for it? I maintain a VM/CMS implementation of news, and need this info to add proper support for this header. It is certainly clear to me the way the header works, but there are some unanswered questions...for example: 1) Can ANYONE issue one of these (not just the author of the original article)? If only the original author may issue it, then do we verify this the same way we verify the posting of 'cancel' requests? 2) Since this does not appear to be a control message, does it need an 'Approved' header? 3) Can you include a 'Supersedes' header on a control message? If so, what does it mean if that control message is a 'cancel', 'newgroup', You get the idea. etc.
