Extension elements and namespace prefixes
I have been playing with the new release of XT which I think is wonderful (thank you James). While adapting my own output handler to work with the new implementation I discovered a `problem' that had escaped my attention before: the name of the element passed to methods startElement and endElement contain the namespace prefix if it wasn't null. previously I always had a null prefix in such cases which is probably why I never noticed the problem. The reason for passing a prefixed name of course is that this is what is mandated by SAX. However it seems to me that this doesn't make sense for extension elements since the prefix is chosen by the stylesheet not by the implementation of the extension. Thus a robust implementation must strip off the prefix (btw, this is not done by XT's output handlers, which means that if they are invoked with an arbitrary prefix they don't work - at least the NXML output handler has this problem). At the moment, I simply look for a `:' in order to strip a prefix if any. My question is: is this the correct way to recognize a prefix? Is the namespace separator guaranteed to always be a colon?
