no schemaType="application/xml-dtd" for jing NRL, right?

As long as jing's NRL implementation can validate documents from multiple
namespaces at once, and it's using Xerces for XSD schemas, I was hoping that
it could use Xerces to validate documents against DTDs as well. The error
message  "fatal: The markup in the document preceding the root element must
be well-formed" for the DTD file shows me that it expects the schema to be
some sort of well-formed XML schema, so I understand. But it would have been
cool. Unless I'm missing something...
