* This class is used to build <code>W3CEndpointReference</code>

* to create an <code>W3CEndpointReference</code> for a
* web service endpoint published by the same
* Java EE application. It can also be used to create
* <code>W3CEndpointReferences</code> for an Java SE based
* endpoint by providing the <code>address</code> property.
* <p>
* When creating a <code>W3CEndpointReference</code> for an
* endpoint that is not published by the same Java EE application,
* the <code>address</code> property MUST be specified.
* <p>
* When creating a <code>W3CEndpointReference</code> for an endpoint
* published by the same Java EE application, the <code>address</code>
* property MAY be <code>null</code> but then the <code>serviceName</code>
* and <code>endpointName</code> MUST specify an endpoint published by
* the same Java EE application.
* <p>
* When the <code>wsdlDocumentLocation</code> is specified it MUST refer
* to a valid WSDL document and the <code>serviceName</code> and
* <code>endpointName</code> (if specified) MUST match a service and port
* in the WSDL document.
