7.  Control Messages

   The following sections document the control messages.  "Message" is
   used herein as a synonym for "article" unless context indicates
   otherwise.

   The Newsgroups-header of each control message SHOULD include the
   newsgroup-name(s) for the group(s) affected (i.e. groups to be
   created, modified or removed, or containing articles to be canceled).
   This is to ensure that the message propagates to all sites which
   receive (or would receive) that group(s). It MAY include other
   newsgroup-names so as to improve propagation (but this practice may
   cause the control message to propagate also to places where it is
   unwanted, or even cause it not to propagate where it should, so it
   should not be used without good reason).

   The descriptions below set out REQUIREMENTS to be followed by sites
   that receive control messages and choose to honour them. However,
   nothing in these descriptions should be taken as overriding the right
   of any such site, in accordance with its local policy, to deny any
   particular control message, or to refer it to an administrator for
   approval (either as a class or on a case-by-case basis). In
   particular, sites Ought to deny messages not issued by the
   appropriate administrative agencies, and therefore SHOULD take such
   steps as are reasonably practicable to validate their authenticity
   (see, for example, section 7.1 below).

   Relaying Agents MUST propagate even control messages that they do not
   recognize.

   In the following sections, each type of control message is defined
   syntactically by defining its verb, its arguments, and possibly its
   body.
