I didn't see this one coming.  I'm a bit confused by the specification.

If we define a media type that is *always* UTF-8, does this count as 
transporting its own charset information?  Should we say that the media type 
SHOULD NOT be included, or that it SHOULD be included with value UTF-8?  Section 
3 implies the latter, but it also talks about media types defining their own 
default encoding.

(This is not an academic question - a W3C group I'm involved with is about to 
submit a registration for a UTF-8 only text/... media type)
