    Martin,

    One question:
    What is FP? I did not see that in the 1998 standard - my impression
    from reading the spec is that TIFF/IT is the all inclusive designation.
    Is that not correct?

    Also, regarding your comment:
    >But, as I commented above, the list in the spec can only be regarded as
    >incomplete, so it might be better to explicitly make it a set of examples
    >and include only some of these?
    It seems better to me to put the complete list that you have provided into
    the spec. One benefit is that it clearly warns readers that each of these
    conformance levels is distinct.

    Regards,
    Ann

    "document-format-version"for PDF/X and TIFF/IT

    Hi Tom

    Responses in-line.
    ....
      Ann's suggested list is almost what we need:
      - I'm not sure what "TIFF/IT" on its own means in that context - did you
      mean 'FP'? I know FP isn't normative in the 1998 standard (it is in the
      2003 revision), but that doesn't stop people using it :-)

      - there's a 2003 revision of 12639 in ballot at the moment, so we need a
      date suffix on all of the above. In theory the P1 subset has not been
      changed in that revision (we tried not leave it unchanged, anyway), but
      I'd feel safer with a date suffix still, although that might complicate
      capabilities reporting somewhat. The revision also adds a new file subtype

      (SD), and a new conformance level (P2). The full list therefore gets a bit

      long:

    TIFF/IT-FP:1998
    TIFF/IT-CT:1998
    TIFF/IT-LW:1998
    TIFF/IT-HC:1998
    TIFF/IT-MP:1998
    TIFF/IT-BP:1998
    TIFF/IT-BL:1998
    TIFF/IT-FP/P1:1998
    TIFF/IT-CT/P1:1998
    TIFF/IT-LW/P1:1998
    TIFF/IT-HC/P1:1998
    TIFF/IT-MP/P1:1998
    TIFF/IT-BP/P1:1998
    TIFF/IT-BL/P1:1998
    TIFF/IT-FP:2003
    TIFF/IT-CT:2003
    TIFF/IT-LW:2003
    TIFF/IT-HC:2003
    TIFF/IT-MP:2003
    TIFF/IT-BP:2003
    TIFF/IT-BL:2003
    TIFF/IT-SD:2003
    TIFF/IT-FP/P1:2003
    TIFF/IT-CT/P1:2003
    TIFF/IT-LW/P1:2003
    TIFF/IT-HC/P1:2003
    TIFF/IT-MP/P1:2003
    TIFF/IT-BP/P1:2003
    TIFF/IT-BL/P1:2003
    (no P1 conformance level of SD)
    TIFF/IT-FP/P2:2003
    TIFF/IT-CT/P2:2003
    TIFF/IT-LW/P2:2003
    TIFF/IT-HC/P2:2003
    TIFF/IT-MP/P2:2003
    TIFF/IT-BP/P2:2003
    TIFF/IT-BL/P2:2003
    TIFF/IT-SD/P2:2003

    But, as I commented above, the list in the spec can only be regarded as
    incomplete, so it might be better to explicitly make it a set of examples
    and include only some of these?

    No, because most TIFF/IT subfile types are not valid TIFF.
