1. The MediatorInInterceptor is for SOAP binding, you can write a similar interceptor for XML binding etc.
2. We call chain.abort at the end of this interceptor to stop any further processing in the dummy service.
3. In this example, implementor1 and implementor2 are published using local transport. This is achieved by using an address like "local://SoapContext/version1/SoapPort". The MediatorInInterceptor looks up ServerRegistry to find endpoints hosted in the server then does the re-dispatch.
4. The MediatorInInterceptor is set to POST_STREAM phase and before StaxInInterceptor, this makes sure it is the very first interceptor to be invoked.
