I don't think I like this much. Unless I've misunderstood
you're proposing that we hide a DOM-walking SAX event
generator behind a SAX property. I can't really see the
benefit of that. Why would you want to access such a thing
via this route rather than by simply creating one directly,

  XMLReader reader = new DOMXMLReader(someDocument);

The earlier proposals I remember seemed more aimed at simply
allowing access to the current DOM node from a Document/Content
Handler. That seems reasonable, (tho' I'm having trouble 
thinking of any real applications).

Could you elaborate on that a bit?
