If that section is in the MIME registration but not the spec of XHTML 
1.0, I am not sure that's right, as the two documents have to be in 
sync..  If it's in both, we hope that they agree, and I'm afraid of 
overlap.

mpeg-4 and mpeg-21 chose to take the route that the mime registration 
was merely a registration, a pointer from the code point (the mime 
type) to the spec.  Is that a problem?
