Those are another type of "unparsed" entity -- a parser reporting that
it _didn't_ parse, rather than that it _mustn't_ parse!  :)

I always took that "unless" clause to apply to relative URIs showing up somewhere
in document content, not in the DTD; all those examples were of that type, and
the rest of that sentence (and paragraph, and section!) clearly applies to URIs as
declared within the DTD, not to any of the cases in that clause's examples.

A simpler way to put that:  application level URIs are out of scope.  "xml:base"
can legally affect how an "xhtml:href" instance is interpreted, because that's
being done by the application not by the XML processor.
