I think the main point that John makes, that there should be just one
document defining TIFF-FX, is the critical point. The advantage of quickly
generating a document defining "safe" TIFF-FX is specious since many
companies, including the companies with which NetSilicon works, already are
shipping equipment which includes advanced TIFF-FX. The consensus on what is
"safe" will be colored by the fact that no one wants to agree to a
definition that makes their existing equipment nonstandard. By fully
defining all existing and planned TIFF-FX variations as John suggests, a
clear statement is made about what variations exist and how each is to be
identified. Fragmenting this information in multiple documents will lead
to confusion, which is contrary to the purpose of a standard. We also
believe that a single document will, in the last analysis, provide for a
faster consensus on the more feature rich modes which are necessary to make

Yes, a good idea. One document is better for all implementers, I think.
But, how do we separate is the discussion issue.

Right. We need to avoid spending time for our market.
Thanks for your comment.
