Is the use of tag 65535 already in somebody's code? If not, it might
be wise to reserve a private tag ID from Aldus, which avoids the danger
of encountering images with incompatible tags of the same ID (65535 is
a likely candidate for this hazard). Aldus allocates them in blocks of
5, and it only takes a day or two to get them.

I'm not sure who handles the TIFF tag registry now (it used to be Andy
Commons) but you might try Steve.Carlsen@aldus.com for starters.
