Who is that, exactly?  (If you're speaking of Wang, I thought they
had been convinced to switch to TN#2; it'd be disappointing to hear
that they backslid.)

One possible way to lobby such a holdout is to ask them exactly what
interpretation of TIFF 6.0 they use, then walk them through the
ambiguities cited in TN#2; then you can ask them if they think they're
really improving compatibility with anything else by sticking to

It's supposed to be in TIFF 7.0.  The problem is that Adobe is expending
zero resources on maintaining the TIFF spec; they promised a TIFF 7.0
draft many moons ago, but it has never appeared, and I lack any
confidence that it ever will appear from them.

Perhaps those who care about the future of TIFF ought to mount a
lobbying campaign to get Adobe to turn over ownership of the TIFF spec
to someone who will take better care of it.  They've demonstrated that
they don't care about TIFF, so maybe they'd be willing to give it up.
