As we have just cleared up .. there are two image/tiff application types.

We should stick to what IANA should have posted.

Then I agree as well that "tiff-profiles-supported" would be a proper
additional attribute to develop.

And there are 6 profles.

Profile S, F, J, C, L and M

To quote from what should have been in the IANA registry.

New Value(s): faxbw, faxcolor

Description of Use:

faxbw - The "faxbw" application parameter is suitable for use by
applications that can process one or more TIFF for facsimile profiles or
subsets used for the encoding of black-and-white facsimile data.

faxcolor - The "faxcolor" application parameter is suitable for use by
applications that can process one or more TIFF for facsimile profiles or
subsets that can be used for the encoding of black and white, AND color
facsimile data.

This seems quite reasonable.
