Re: @xml:base with @rendition (and maybe other pointers)

Where does it say the interpretation of a fragment ID *with respect
to its @xml:base* depends on the media type?

Yes, I think a base URI is specific to an element (which might be the
whole document, might not).

Yes, I think the quoted passage is saying that a fragment ID points
to the same document as the base URI in effect.

No, I'm not at all sure the paragraph in the xml:base spec does say
that fragment IDs should honor the xml:base. But then again, I'm not
at all sure it *doesn't* say that.
