Thanks Ant for your reply. Much appreciated. We are currently utilizing Tuscany 1.5.1 on WAS v7 (under the IBM provided SCA feature pack). So ideally we would need it under 1.5.1....but that might not be ideal for you obviously. I was wondering about custom extensions as well. It looks like the wire format allows a custom wire format to be defined. This doesn't seem to be quite the right spot though. The wire format code uses a request and response message processors. Would this be the right spot? Is there any way to provide a custom one of these?

Its interesting though and seems like a reasonable thing to support. The spec doesn't disallow this so we could easily enough add some code to the Tuscany binding to handle it (I'll also mention it to the JMS spec chair to see if this is something they've considered). If we did update Tuscany to support this would you need this is 1.x or if it only went into the latest OASIS based Tuscany 2.x code would you be able to use that? ...ant
