RE: MIME types and fragment identifiers in HTML and XML

We're making up things about fragment identifiers. The only existing
ones are the ones that work with HTML, and *those* certainly don't
identify things with media types. If you point at an 
<H1><A NAME="ab">This is a heading marked 'ab'</A></H1>, what is
the type of the fragment inside the H1? It's not 'text/html'.

By extension, I don't think fragments have media types. That's why
they're fragments.

I don't think fragments can or should have media types. Content-type
media types in MIME are for identifying the application semantics
intended by an entire message body, and not for denoting anything
about the types of components of that body.
