I'm not sure I understand -- how would a SAX filter help the DOM? If you are 
building a DOM tree from SAX 1.0 events, there are no entity references, 
etc. -- the most you could get is multiple text nodes (from multiple 
callbacks to DocumentHandler.characters()), which the normalize() method can 
handle. (There is also a SAX filter somewhere that bundles multiple calls to 
character() into a single call.) Similarly, if you were generating SAX 1.0 
events from DOM, the most you could get is multiple calls to character().
