I've been talking to an application vendor, who claims that all the
output from their system is to TIFF 7.0 spec.  Which they are aware
not all viewers handle, but they use anyway.

I queried this, and was assured that the TIFF 7 spec is only available
if you buy it from Adobe, and therefore they couldn't/wouldn't tell me
any more.

I thought TIFF 7 was presented back in the 90s as a draft spec but
never went any further, aside from periodic attempts to resurrect it,
which fail...
I was under the impression the current spec was TIFF 6.0 amended by a
couple of tech notes which add in extra compression type support and
maybe a couple of tags, but that was that.

Am I wrong?  Is there a 'secret' Adobe TIFF 7 spec?  In which case why
the secrecy?  It's not like they use it as a core file format for
anything.
