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

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

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.
