Ah, I misunderstood you.  I thought you were referring to a separate
media type for the embedded RNG itself, not for use by the referrer to
that RNG.  I wouldn't encourage the referrer to use a separate media
type since it violates the principle that the server provided media type
be authoritative in determining fragment identifier.

I agree with your premise that a new media type for each new XML
vocabulary is not a scalable, long-term solution.  But neither do I
think that application/xml is a solution.  The work being done in the
CDF WG may provide one, but for now though, I agree with Liam and
Martin that a new media type makes the most sense.

Mark.
