* This object is set to {@link Packet#webServiceContextDelegate}
* to serve {@link WebServiceContext} methods for a {@link Packet}.
*
*
* When the user application calls a method on {@link WebServiceContext},
* the JAX-WS RI goes to the {@link Packet} that represents the request,
* then check {@link Packet#webServiceContextDelegate}, and forwards
* the method calls to {@link WebServiceContextDelegate}.
*
*
* All the methods defined on this interface takes {@link Packet}
* (whose {@link Packet#webServiceContextDelegate} points to
* this object), so that a single stateless {@link WebServiceContextDelegate}
* can be used to serve multiple concurrent {@link Packet}s,
* if the implementation wishes to do so.
*
*
* (It is also allowed to create one instance of
* {@link WebServiceContextDelegate} for each packet,
* and thus effectively ignore the packet parameter.)
*
*
* Attaching this on a {@link Packet} allows {@link Pipe}s to
* intercept and replace them, if they wish.

* Gets the address of the primary WSDL.
*
*
* If a transport supports publishing of WSDL by itself (instead/in addition to MEX),
* then it should implement this method so that the rest of the JAX-WS RI can
* use that information.
*
* For example, HTTP transports often use the convention {@code getEPRAddress()+"?wsdl"}
* for publishing WSDL on HTTP.
*
*
* Some transports may not have such WSDL publishing mechanism on its own.
* Those transports may choose to return null, indicating that WSDL
* is not published. If such transports are always used in conjunction with
* other transports that support WSDL publishing (such as SOAP/TCP used
* with Servlet transport), then such transport may
* choose to find the corresponding servlet endpoint by {@link Module#getBoundEndpoints()}
* and try to obtain the address from there.
*
*
* This information is used to put a metadata reference inside an EPR,
* among other things. Clients that do not support MEX rely on this
* WSDL URL to retrieve metadata, it is desirable for transports to support
* this, but not mandatory.
*
*
* This method will be never invoked if the {@link WSEndpoint}
* does not have a corresponding WSDL to begin with
* (IOW {@link WSEndpoint#getServiceDefinition() returning null}.
*
* @param request
* Always non-null. See class javadoc.
* @param endpoint
* The endpoint whose address will be returned.
*
* @return
* null if the implementation does not support the notion of
* WSDL publishing.
