MIME type registration notes

My review of the relevant documents is available in <http://students.washington.edu/rfritz/radreg/ >; there's an annotated RFC (in PDF format) and a proposed registration form. If anyone would care to take a look (Axel?) and see if I've missed anything obvious, please let me know. The directory is passworded to keep it from showing up in Google; the username/password is rad/rad.
