As you know, Axis2 assumes that every message it processes is
representable as XML (which is different from CXF where a message can
have different representations, depending on the phase that is
executed). Until now this has always been the case, even for plain
text and unstructured binary data. Are you going to drop that
requirement from the Axis2 architecture or else, what would be the XML
representation of a JSON message received by that message receiver?
