If its optional and not present, then application/xml has some rather
unworkable ideas for the results. So, its better not to be allowed, in
fact.

I appreciate your concern. Sorry, we thought that "The MIME type for
SVG is "image/svg+xml" (see [RFC3023]). The W3C will register this
MIME type around the time when SVG is approved as a W3C
Recommendation." gave everyone the information they needed.
http://www.w3.org/TR/SVG/intro.html#MIMEType

Also, in the future, W3C specifications will be expected to develop
the MIME registration at the same time as the specification itself;
to list it as a normative appendix so it gets the same review as the
rest of the specification. We would also like to see the appendix
accepted as a registration document by IANA.

Hopefully this will break the deadlock whereby

1) x- media types are discouraged
2) media types must be registered before use
3) media types ned to referencea stable document, ir a Rec
4) to get to Rec, you need to show implementation experience at candidate rec
5) to show interoperable implementations, you need a mime type
6) goto 1
