I don't know if this is a previously discussed topic, but does JBossMQ plan to support a TextMessage extension for XMLMessages? If so, does this include being able to create message selectors based on an XPath?
I know SonicMQ and WebLogic JMS support XMLMessages.
The JBossMQ source code is available! Submit a patch that Includes this new feature and it will get added to the standard JBossMQ dist.
