A bigger issue is that even user-agents which *do* process external DTD
subsets are not necessarily going to support named entities; simply
because XHTML5 documents do not link to a suitable DTD defining the
named entities.

In Safari? That's news to me. Last time I tried looking at an XHTML+RDFa
1.0 document served with an XML media type, named entities did not work.
(The XHTML+RDFa 1.0 DTD defines the same set of entities used in XHTML
1.1.)
