RE: Which parser is used when document() is called?

You might find that Xalan uses the parser given by the
javax.xml.parsers.SAXParserFactory system property; on the other hand, to
use that you have to implement a SAXParser rather than merely an XMLReader.
The URIResolver technique is probably better and more portable. You can find
URIResolver in the JAXP documentation.

Something like:

    transformer.setURIResolver(new UserURIResolver());
...

    public static class UserURIResolver implements URIResolver {

        public Source resolve(String href, String base)
        throws TransformerException {
            if (href.endsWith(".xxx")) {
                try {
                    URL url = new URL(new URL(base), href);
			  SAXSource ss = new SAXSource();
                    ss.setSystemId(url.toString());
                    ss.setXMLReader(new MyOwnParser());
                    return ss;
                } catch ...
            } else {
                return null;
            }
        }

    }
