Specified in the XML file using DOCTYPE ???

No, AFAIK. If there's no DOCTYPE declaration, your parser won't
validate. Simple as that.

If there IS a DOCTYPE declaration, you can fiddle it with XML Catalogs
(see Norm Walsh's code in xml-commons). If there is no DOCTYPE
declaration, Catalogs won't work.

So.. (tada..) my solution :)

Lets you add, remove, modify (conditionally), and otherwise play with
the DOCTYPE declaration on an incoming XML stream, *before* the parser
gets to it.

As long as you're dealing with 8 bit chars, that should work fine.
