I didn't say that well...presumably the subject of an XRD could be a
resource or it could be an abstract thing identified by the URI. I was
speaking more to the latter.

If it's an actual resource, then I would assume the the fragment would have
meaning relative to the MIME type that results, as usual, and that the XRD
would be about that subset of content, and not the whole resource.

If not, then I guess I'd suggest precluding fragments, because it wouldn't
make sense for two different Subjects differing by fragment to be meant as
the same thing.
