I disagree -- there is nothing in RDDL itself which prevents it being used
to describe the resources associated with a document type. The problem is
that XML has no built in way of specifying the resource which is that
document type -- the system identifier in the DOCTYPE declaration is too
strongly tied to DTD retrieval to be usable for the purpose.
I think the W3C takes the view that there is nothing interesting to be said
about a document type as a whole which is not simply an assembly of the
statements you can make about the element types in that document. I'm not
sure whether I agree with this, but it's not an RDDL issue.
I suppose one could try to establish a convention that, on the root element
of a document, something like
<root
xmlns:dt="http://www.doctype.org/";
dt:doctype="http://myorg.com/some-doctype";
>
specifies the type of the document as a whole. If this were done, it would
make perfect sense for this dt:doctype URI to point at an RDDL document.
