There's been talk about Microsoft tags in the past, possibly this
includes yours. Searching for 'microsoft tags ulf' over at
http://www.awaresystems.be/imaging/tiff/tml.html may lead to posts from
Ulf Zibis that may be useful.

I've finally defenetly decided against adding tags for which no
information is available, like (some of?) the Microsoft tags, simply on
the basis that they've been 'spotted'. If no info is available, they're
unknown, and if they're unknown, they're unknown like any of the
thousands of other tags not included in the directory of known tags.
There's no point in making the JavaScript search index file even heavier
for these tags, since I suspect it's rather big already for users
without broadband connection, and there's nothing useful to gain from it
in the absence of real information.

However, if you come accross any defenite documentation for any of these
tags that is not a result of spotting and/or reverse engineering, or you
know of anyone or any helpdesk or whatever that might be persuaded to
release information on the tags, please do notify me, and I'll be happy
to put in whatever work it takes and include them in the directory.
