7.2.1.  Proto-articles

   A proto-article SHOULD NOT be propagated in that form to other than
   injecting agents.

   A proto-article has the same format as a normal article except that
   some of the following mandatory headers MAY be omitted:  Message-Id-
   header, Date-header, Path-header (and even From-header if the
   particular injecting agent can derive that information from other
   sources).  However, if it is intended to offer the proto-article to
   two or more injecting agents in parallel, then it is only the Path-
   header that MAY be omitted.  The headers that can be omitted MUST NOT
   contain invalid values; they MUST either be correct or not present at
   all.
[Maybe omit that last sentence.]

        NOTE: An article that is offered for reinjection has, by
        definition, already been injected once, and is not therefore to
        be considered as a proto-article.  Hence a genuine proto-article
        will not contain any Injection-Date-header nor any '%' path-
        delimiter in its Path-header. It MAY contain path-identities
        with other path-delimiters in the pre-injection portion of its
        Path-header (a-5.6.3).
