In SAX or DOM mode, Xalan should currently be able to handle any namespace-aware parser.
If you're letting us instantiate the parser, we will attempt (via reflection) to take advantage of some of Xerces' internal features, but if we don't find Xerces2 we should fall back on Xerces1, and if we can't recognize it as Xerces1 we should fall back on JAXP and SAX. (At some point, I think we ought to rip out the explicit support for Xerces1 -- I know I don't intend to put a lot of work into ongoing support for that code, and it's a distraction when trying to maintain the Xerces2 support. We can always fall back on generic SAX.) ______________________________________ Joe Kesselman / IBM Research
