3.2  Optional Headers

   None of the headers appearing in this section is required to appear

   articles in the same circumstances and with the same meaning as that
   specified in [RFC2822] with the added restrictions detailed in
   Section 2.2.  Multiple occurances of the Keywords header are not
   permitted.

   comments        =  "Comments:" SP unstructured CRLF

   keywords        =  "Keywords:" SP phrase *("," phrase) CRLF
