4.2.2.1. Experimental Headers

4.2.2.1.  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. There
   are no established headers (see 4.2.1) that are considered
   experimental headers; an established header cannot be experimental.

        NOTE: Some such headers may eventually be adopted as standard by
        some extension to this standard, at which point they will lose
        their "X-" prefix.
