Solicit Response And Notification in WSDL 1.1

        Hi,
WSDL has four transmission primitives  (Section 2.4, WSDL 1.1 ) that an endpoint (say X) can support-
*       One-way. The endpoint X receives a message. 
*       Request-response. The endpoint X  receives a message, and sends a correlated message. 
*       Solicit-response. The endpoint X sends a message, and receives a correlated message. 
*       Notification. The endpoint X sends a message. 


In case of Solicit-response, WSDL for endpoint X, would look like as follows: 

<wsdl:definitions .... >
    <wsdl:portType .... > *
        <wsdl:operation name="A" parameterOrder="nmtokens">
           <wsdl:output name="nmtoken"? message="qname"/>
           <wsdl:input name="nmtoken"? message="qname"/>
           <wsdl:fault name="nmtoken" message="qname"/>*
        </wsdl:operation>
    </wsdl:portType >
</wsdl:definitions>

In case of Notification, WSDL for endpoint X, would look like as follows:.

<wsdl:definitions .... >
    <wsdl:portType .... > *
        <wsdl:operation name="B">
           <wsdl:output name="nmtoken"? message="qname"/>
        </wsdl:operation>
    </wsdl:portType >
</wsdl:definitions>


Now an endpoint (say Y ), needs to communicate with X using it's WSDL.

In case of Solicit-Response and Notification, the endpoint X would send some message to endpoint Y.

Now, I have following queries:-

1) Who has (X or Y) implemented the operations A and B?
2) Who would call (X or Y) the operations A and B?

Any help would be greatly appreciated!

thanks,
regards,
