Hmm..understand that the transport mechanism is independent of the message being transfered. But then, isn't the payload commonly XML based. XSD based can mainly offer structural validations like if an element is present and its data type, right? Is there some example for custom Actions, where a message is broken down for certain business validations? Also, are MessageFilter, Drools used for validations?
