hi Anne,

thanks for looking into it. how do i know that service described in WSDL 
supports WSA and that it will respect ReplyTo to send response 
asynchronously? the [2] describes how to send SOAP message by adding WSA 
required headers but i could not find how to know that for some service 
described in WSDL it is required to use WSA or not allowed as it does 
not support WSA or it does not allow async responses (only RPC).

i looked on [1] but i could not find by reading WSDL if the service 
supports WSA (or async operations)?

one heuristic i thought would be too look for wsa:Action inside 
wsdl/portType/operation/* but it does not seem to be the best or very 
reliable way to do it - is there any better way?
