    I agree completely with John Pulera's recommendation for one document and
    Bill Wagner's recent comments. The Printer Working Group has been making
    very good progress on the IPP FAX initiate and I believe that, unless there
    remains a unified document, this effort will suffer serious delays.

    What really surprises me on this subject is the fact that RFC 2301 was
    officially published in March 1998, with public drafts available in late
    1997, and this is only now a major issue. Be that as it may, we need to now
    quickly devise a plan that satisfies both Adobe and Xerox, but does not
    scrape all the work on the TIFF-FX extensions.

    Tamura-san,

    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
    IFAX viable.

    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.
