Issue 28 - Multiple ports needed in an EPR
According to the ws-addressing submission, "Endpoint references convey the information needed to identify/reference a Web service endpoint, and may be used in several different ways: endpoint references are suitable for conveying the information needed to access a Web service endpoint...."  However, in the situation where there are different protocols/transports/formats available for the same service, the "access to a Web service endpoint" requires the client to choose among alternatives, each accessible in the standard manner through a port - but there are different ports for each protocol/transport/format alternative.  When such alternatives exist, the EPR must be able to identify those multiple ports.
