Some combination of the two.

(a) I'm inclined to update the HTML media type spec to say
that in a document with head/@profile present, what
fragments refer to is not necessarily sections of the document;
it's whatever the profile says it is (e.g. baseball players
discussed in the document, etc).

(b) publishing only RDF without the HTML is pretty useful.
If you decide later that you want HTML, you can add it.
Note that it suffices to do a 303 redirect for .html;
you don't need to redirect in both cases. You can
just return the RDF in a 200 response to GET /doc .
