Implementing 'WS Reliable Messaging' with Spring WS

Hi
Greetings,

We have a new requirement, host a "WebService which supports Reliable Messaging using Spring WS". I 'd like to know if Spring WebServices supports WS-Reliable Messaging? I've checked the documentation but found nothing on this.
We must support Reliable Messaging with our Spring WebServices, please help us is there any way to support Reliable Messaging with Spring WS.

We are not supposed to use CXF.

Any help much appreciated.
Thanks in advance.

Regards,
Siva...
