Isn't the parser creation exposed now after Alex's breakout of the
builder, specifically in the createParser() method?

Yes, if I have my way.  :-)

I think using the SAX parser that's already there to do the DTD parsing
makes sense at least in the near term.  Can you check if the
createParser() method provides enough of a hook for you to do what you
need?
