4.2.5.1.  Experimental Headers

   Experimental headers are those whose header-names begin with "X-".
   They are to be used for experimental Netnews features, or for
   enabling additional material to be propagated with an article. They
   are not (and will not be) defined by this, or any, standard.

        NOTE: Experimental headers are suitable for situations where
        they need only to be human readable. They are not intended to be
        recognized by widely deployed Netnews software and, should such
        a requirement be envisaged, it is preferable to use a normal
        header on the provisional basis set out in section 4.2.1.
