As part of the Microsoft Office Documenting Imaging investigation, I've come across a couple of tags that aren't being recognised by tiffdump:

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 checked for these tags at http://www.awaresystems.be/imaging/tiff/tifftags.html, but not got any hits.

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.
