[OT] Pondering over ContentHandler's startElement

[Dave Brosius]

This question probably has been asked many times before, and i realize it's beyond xalan's devs to be the authority on everything sax, but indulge me if you wouldn't mind.     Was there any consideration to have the startElement signature return a boolean which informed the parser as to whether or not the client wanted to be notified of sub tree events? Seems like it would be a handy thing.
