Hi Mark,

You've written up your request for new PDL enumerations (below).  Now you
want Printer MIB WG comments.  So I enhanced the Subject of this reply,
to label your request.

Last year, the IPP WG decided IANA MIME types SHOULD be registered for
all PrtInterpreterLangFamilyTC enums that_are_currently_in_use (not any
obsolete ones), so that those PDL types can be used with IPP, Bluetooth,
UPnP, and other printing protocols.  So any _new_ PDL enums should also
have MIME types registered.  Would you please research if any of your
proposed additions _do_ have IANA MIME types registered?

If not, we would appreciate the necessary information for IANA MIME type
registration for each new PDL filled into the template specified in
Section 2.8 'Registration Template' of RFC 2048 "MIME Part Four:
Registration Procedures".

Some questions about your proposal below:

1)  Are VRASTER, VDS, and VCGL different PDLs?  If so, they need to be
    be separate enums.  Only _versions_ of the _same_ PDL should ever
    use the same enum.
2)  'langDoD' (which should be 'langDOD') is very ambiguous.  Is this a
    a graphics format (like your other new enums)?  It's seems likely
    that the US Dept of Defense has _document_ format standards as well,
    so the proposed name of this enum isn't specific enough.
3)  Are CALS1, CALS2, and C4 different PDLs?
    See (1) above.
4)  Need more info about CALCOMP plotters.  What's PDL language name?

Cheers,

Subject: Printer MIB v2

Xerox Engineering Systems would like to add the following enumerations to
PrtInterpreterLangFamilyTC in the Printer MIB:

langCALCOMP             -- Calcomp plotters
langDoD         -- US Dept. of Defense specifications
                        -- includes CALS1, CALS2, and C4
langVERSATEC    -- Versatec plotters
                        -- includes VRASTER, VDS, and VCGL
langJPEG                -- Joint Photographic Experts Group
langCGM         -- Computer Graphics Metafile (ISO 8632)

The printer MIB v2 says:

      enumeration (2)  An initial set of values are defined in the
      Printer MIB specification.  Additional enumerated values are
      registered after review by this working group. The initial
      versions of the MIB will contain the values registered so far.
      After the MIB is approved, additional values will be registered
      through IANA after approval by this working group.

Could someone tell me the process for obtaining working group agreement?

Thanks,
