/**
* This is a generalization of org.apache.cxf.jaxws.EndpointReferenceBuilder and org.apache.cxf.jaxws.EndpointImpl
*
* <p>
* javax.xml.ws.WebServiceContext org.apache.cxf.jaxws.EndpointReferenceBuilder doesn't expose the API for adding
* additional metadata while org.apache.cxf.jaxws.EndpointImpl doesn't take the correct endpoint address from the
* EndpointInfo object. org.apache.cxf.endpoint.Endpoint return a CXF proprietary endpoint reference and not the
* javax/w3c standard definition.
* </p>
*
* <p>
* This interface is intended to provide an abstract way to construct an endpoint reference for a given service,
* depending on the type of endpoint interface you have at hand (CXF abstract endpoint or jaxws endpoint)
* </p>
*
* <p>
* Normally the type parameter T will be bound to your endpoint type.
* </p>
*
* <p>
* In CXF jaxws applications you can easly get a WebServiceContext instance which returns an EndpointReference, however
* the API is cumbersome because it requires instantiating w3c DOM Element instances for each reference parameter, and
* it doesn't allow setting custom metadata elements.
* </p>
*
* <p>
* Implementors of this API will extract as many useful informations from the runtime besides the plain soap endpoint
* address.
* </p>
