Except for adding full namespace support. However, we have removed
entities, which are in DCD. As my other posting says, DCD is
required to be a superset of DTD, whereas XSchema is not.

It does add new information, but not all that much: namespace
support, datatypes, value ranges. In addition, DCD is silent about
notations.
There is a large common semantic core between DCD and XSchema.
The efforts ought to be merged, providing something that is
compliant RDF, supports the common element/attribute core,
the value ranges, at least some of the datatypes, unparsed
entities, and notations.
