It is the right place only in a private system. That is, if the author
uses a tool that parses the DTD and reserializes the document either as
DTDless XML or as text/html soup for delivery over the public network.
I think user agents should not be required to use XML processors that
parse the DTD. Also, authors should not be given the impression that
entities (other than the 5 predefined ones) are suitable for use on the
Web when the content is parsed as XML. (I consider the inclusion of the
HTML 4 entities in the XHTML DTDs as a serious spec bug.)
Of course, in the tag soup mode (text/html) the HTML 4 entities are
available regardless of the DTD.

If WHAT WG decides to endorse a formalism for (partially) assessing
syntactic conformance, I'd prefer Relax NG on the XHTML side.
