5.4.  Subject

   The Subject-header contains a short string identifying the topic of
   the message. This is an inheritable header (4.2.5.2), normally to be
   copied into the Subject-header of any followup with the possible
   addition of a back-reference as described in B.6.

      header              =/ Subject-header
      Subject-header      = "Subject" ":" SP Subject-content
      Subject-content     = unstructured

        NOTE: The syntax of unstructured differs from that prescribed in
        [RFC 2822], so ensuring that the Subject-content is not
        permitted to be completely empty, or to consist of WSP only.
