Are these standards too new to be adequately documented?  Are they controlled
by patent-enforcing companies which are aggressive litigators?  

I DID try to find some reference images as well as a complete specification,
but didn't find much at all.

Understood.

Ouch.  Adobe is usually pretty good about supporting formats, at least with
decoding them.

Excellent, excellent.  Merci beaucoup, mon ami généreux.

I understand.  It seems that the standard is too new and emergent to be very
useful outside a very limited scope.  I'm puzzled as to why it was embraced
and adopted by the facsimile hardware vendors.  Designing a "modern" facsimile
system without computer-based documents management and processing firmly in
mind seems mentally deranged.
