6.13.2.  Message-ID version procedure

   Whilst this procedure is not essential for the operation of Netnews,
   it SHOULD be supported by all serving agents. However, for the
   procedure to work, all the msg-ids in the Replaces-content MUST be
   those of successive replacements of the same original article, and
   all be generated as described below.
[Whilst the procedure about to be described will undoubtedly work, it
must be pointed out that life would be much simpler if there was only a
single msg-id allowed in a Replaces-content.]
