6.4.  Keywords

   The Keywords field contains a comma separated list of important words
   and phrases intended to describe some aspect of the content of the
   article. The content syntax makes use of syntax defined in [MESSFOR].

      Keywords-content    = phrase *( "," phrase )

        NOTE: The list is comma separated NOT space separated.

-     ment has found the contents of Keywords headers to
