It depends on your approach.  Personally, I don't like the JAXP method for obtaining an XMLFilter because it precludes the setting of parameters on the Transformer.  (The right way to do that, btw, IMHO, would be to map SAX properties of the form[qname] to the Transformer properties, but I digress...)

Another way to hand an XMLReader (or XMLFilter) to an XSLT processor using TrAX is to wrap it up in a SAXSource:

	// Foo implements XMLReader
	XMLReader xr = new Foo();
	InputSource is = new InputSource(blahblah);
	SAXSource sxs = new SAXSource(xr,is);

(Get a new Transformer here...)

Since it appears that you want serialized output, I'd suggest just using a StreamResult instead of a serializer:

	StreamResult str = new StreamResult(System.out);

As for your specific code, I don't see anything obviously wrong.  (Maybe I'm missing the obvious...)  Does your XMLFilter implementation pass-on namespace and other SAX property settings to the driving XMLReader?  (Xalan can be a little picky about which way it receives namespace events.)
