	From Xerces documentation:
	it is up to the application whether to throw an exception
	for different types of errors and warnings. Note, however,
	that there is no requirement that the parser continue to
	provide useful information after a call to fatalError (in
	other words, a SAX driver class could catch an exception
	and report a fatalError).
	We weren't throwing exception before.
