As I have already said in the WSDL attributes TF, WSDL is not the right
place to introduce semantics like this. WSDL is the specification on
_how_ to write WS interfaces and not what the behavioural semantics of
those interfaces are.

SOAP is definitely not the right place since it's just a wire protocol.

If stateful interactions are required and none of the current approaches
are suitable (WS-Coordination, WS-Conversation, etc.), then a new WS-*
standard will have to be formed that it's adopted by the community
(WS-StatefulInteractions?... I don't know).

IMHO, WSDL is definitely not the right place.
