    Hi Jim,

    Thanks very much - we just want the authoritative reference(s)
    for the PDL formats - we expect implementors (not editors) to
    actually read them.

    I will do the research as far as I can without actually reading
    the standards documents. Assigning MIME types under the vendor
    tree sounds like it could work, but I don't think we have anyone
    to take the roll of change master for the DOD specifications.
    Since I have not read the specs and have no intention of
    reading them, I can't be an authoritative source.
