6.10.  References

   The References-header is an inheritable header (see 4.2.5.2) which
   lists CFWS-separated message identifiers of the article's precursors,
   as described in 8.6.  The content syntax makes use of syntax defined
   in [RFC 2822] (but see the revised definition of msg-id in section
   2.4.3).

      header              =/ References-header
      References-header   = "References" ":" SP References-content
      References-content  = [CFWS] msg-id *( CFWS msg-id ) [CFWS]

        NOTE: This differs from the syntax of [RFC 2822] by requiring at
        least one CFWS between the msg-ids (a SP at this point was an
        [RFC 1036] requirement).

   A followup MUST have a References-header, and an article that is not
   a followup MUST NOT have a References-header.
