[cddlm] dumping failing CDL test docs to files

Jun, Ayla and anyone else running the CDL test cases I'm finding I have to extend the Test code to dump the in and out docs to the output stream. That way I can diagnose the problems I'm having. Question is, 1. do I try and get the DOM3 APIs to work consistently, and use the dom3 factory stuff, that never seems to work well for me. 2. or can I assume that everyone is running Xerces and use their API 3. or do I extend the CdlSmartFrogProcessor to let everyone provide their own dump() operation to save the doc to a PrintStream? I'm biased towards (3) as I have all the code to serialize something under Xom working, and hate working with dom. Comments? -steve see: http://xerces.apache.org/xerces2-j/faq-dom.html#faq-3
