		dom_string *	attr_name,
		dom_mutation_type	change,
		bool *	success
	)

DOM_NO_ERR on success, appropirate dom_exception on failure.

__dom_dispatch_characterdata_modified_event()

dom_exception __dom_dispatch_characterdata_modified_event	(	dom_document *	doc,
		dom_event_target *	et,
		dom_string *	prev,
		dom_string *	new,
