    Hi Ron,

    I vote we accept these new PDL registrations below. James Babcock
    has provided us with all of the MIME types, so documentation is

    I'll be happy to write up the new fragment of the TC to add these
    six, if you want. Then we can fold them into our new draft for
    the RFC Editor in the immediate future.

    Hi again Ira.

    I would like to request the following additions to

    Language Designator Associated MIME type
            CGM image/cgm
            JPEG image/jpeg
            CALS1 application/cals-1840
            CALS2 application/cals-1840
            NIRS (aka NIFF) application/cals-1840
            C4 application/cals-1840

    As you can see, the last four languages correspond to a single
    MIME type. The four languages are specified in different
    sections of a single document (MIL-PRF-28002). The document
    falls under a broader standard document designated as
    MIL-STD-1840. To me it doesn't appear that the idea
    of different level designations for languages applies to
    these four items, but that decision is up to the PWG.
