Actually, I looked at 2616, and it doesn't disallow text/xsl
because 2616 just defined the general syntax and then says
"Use of non-registered media types is discouraged" which
is like a "should not".

So, if I'm reading all this right, our current wording does
not disallow type="text/xsl".

Given that Mike thinks it does, I suppose that argues even
more strongly for the need of an informative note.
