Sounds like a good idea. I like XMLizable better, so lets go with this
one. Except that we would need to have toSAX(ContentHandler) as well
in this interface:

public interface XMLizable {
   void toSAX(ContentHandler handler) throws SAXException;
   void toSAX(XMLConsumer consumer) throws SAXException;
}

Other thoughts?
