Hmmm.. We do plan to implement DOM L3 specs and although we did not
discuss implementing Abstract Schema [AS] module (that allows editing
and querying grammars), the APIs are there. Do we want to provide
another way to access grammar??
I am not sure how DTDContentModelHandler is useful for editor writers.
In the world of XML Schemas, you better also provide support for editing
XML Schemas as well as DTDs, and DTDContentModelHandler provides way to
little information..
My point is, I believe if we ever want to provide in Xerces APIs for
editing/querying AS (DTD, XML Schemas, other grammars), we better do it
by implementing standard DOM APIs.

Can baseSystemId be null?

If we are removing dependence on SAX, should we consider using DOM L3
APIs for error handling, entity resolver, input source?
Andy, you've mentioned that SAX raises a lot of problems, could you
expand on that? ..I am not sure why do we need to define again the same
interfaces that exist in both DOM and SAX??
Thx,
Elena
