Hi Guys, another topic I'd like to discuss with you: We should support multiple versions of the following specs: [SHOULD] WS-Addressing [SHOULD] WS-Policy [NICE] WS-ReliableMessaging I know, we already support WS-Addressing multiple versions. To achieve this we just need to add another spec builder there. But I mean to make it possible to use multiple WS-Addressing versions / per JVM. This is prohibited in current architecture :-( Cheers, Richard
