/**
 * An EndpointDescription corresponds to a particular Service Implementation. It can correspond to
 * either either a client to that impl or the actual service impl.
 * 
 * The EndpointDescription contains information that is relevant to both a Provider-based and
 * SEI-based (aka Endpoint-based or Java-based) enpdoints. SEI-based endpoints (whether they have an
 * explicit or implcit SEI) will have addtional metadata information in an
 * EndpointInterfaceDescription class and sub-hierachy; Provider-based endpoitns do not have such a
 * hierachy.
