A newer version of the Annotation Specs can be found at http://www.eistream.com/support_PRO/faqs/annospec.htm.
I was hoping someone would post some additional information... :-> I believe there are at least a couple of other proprietary tags: 33000 and 32934. The latter seems to appear in annotated images, but I haven't really looked into it.
There is a couple of additional statements about their formats (including TIFF) at http://www.eistream.com/support_pro/faqs/pro_format.htm.
