3.2.5  Supersedes

   The Supersedes header contains a message identifier specifying an
   article to be superseded upon the arrival of this one.  An article
   containing a Supersedes header is equivalent to a "cancel" [USEPRO]
   control message for the specified article, followed immediately by
   the new article without the Supersedes header.

   supersedes      =  "Supersedes:" SP [CFWS] msg-id-core [CFWS] CRLF

   NOTE: There is no "c" in Supersedes.

   NOTE: The Supersedes header defined here has no connection with the
   Supersedes header that sometimes appears in Email messages converted
   from X.400 according to [RFC2156]; in particular, the syntax here
   permits only one <msg-id-core> in contrast to the multiple
   <msg-id-core>s in that Email version.
