DTDs are not in the XPath data model. DTDs are not well-formed XML.
Ken Holman added: In Annex F of XSLT you will see the
wish list includes "support for DTDs in the Data Model"
which is what you want.

Access to the DTD
Mike Brown
In XSL, you don't have access to the source document's DTD.

How can I create a DTD using the Oracle parser
Steve Muench
Creating a DTD is done with:
DOMParser d = new DOMParser();
d.parseDTD(xxx);
DTD myDTD = d.getDoctype();
Where "xxx" can be one of:
InputStream
InputSource
Reader
String
URL
You can then:
d.setDoctype(myDTD);
to set and cache that DTD as the one to
use for this instance of the parser.
