Ugh. What's wrong with adding setLexicalHandler? feel free to give the same
object both to it and to setDocumentHandler. Or, if the two are _that_
close, add a getLexicalHandler method to the DocumentHandler interface; it
could return null, 'this', or anything you want. I'd argue that in this case
its better to  simply add the events to the DocumentHandler interface; the
BaseHandler will define them to a no-op anyway.

There's no need to rely on 'instanceOf' kludges.

Share & Enjoy,
