Looks good, Noah.  Have you considered integrating it into the
previous media type registration finding?

http://www.w3.org/2001/tag/2004/0430-mime

I also think it might be useful to say that the community should
attempt to register non-registered types once common practice has been
established... though that probably goes beyond the scope of the
questions asked of the TAG.

Mark.
