 XPAT should probably be documented in an Informational Internet-Draft.

 Maybe PAT could be specified (?)
 Suggestions:

     * The legacy syntax is kept:
       PAT header range|message-ID pattern [pattern ...]

     * New metadata :body to specify that PAT will search in bodies.
       It would be advertised as PAT BODY in CAPABILITIES.

     * Maybe another metadata :text to search in the whole article
 (headers+body)?
       It would be advertised as PAT TEXT in CAPABILITIES.

     * Support for existing :bytes and :lines metadata, like what is
 currently implemented in INN 2.5 (for XPAT):
         XPAT :lines 112- *
         221 Header or metadata information for :lines follows (from
 overview)
         112 7
         113 8
         .
         XPAT lines 112- *
         221 Header information for lines follows (from articles)
         112 A bad Lines: header which is not a number!
         113 1789
         .
