Hi There is more general info on the wire formats for JMS in the 1.x documentation for the JMS binding [1] (we haven't made docs for 2.x yet). Toward the bottom there are some notes about how the feature is implemented.
In 1.x we did add the feature, that Ant is referring to, that allows you to specify wire formats for request and response independently. So, for example, you could have an incoming bytes messages and a response formatted as xml. Ant, is the feature still enabled in 2.x? The wire formats are also pluggable, so in theory you can write your own if the formats that are provided out of the box are not sufficient. As you can see from the docs pages they are basically interceptors that get a chance to process the message as it flows between the binding and the service implementation.
