Quite so.  There is a DTD for Reuters Health's home-grown XML, but all
it is is XHTML (for which there is a DTD and an RNG schema) with RDF
inside the "head" element (for which there is a general RNG schema).
But the XHTML is a tiny subset thereof, and the RDF is laid out in a
very specific way, both of which our DTD reflects.
