javaee:service-ref_protocol-bindingType 

Defines the type used for specifying the URI for the
	   protocol binding used by the port-component.  For
	   portability one could use one of the following tokens that
	   alias the standard binding types:

	    ##SOAP11_HTTP
	    ##SOAP11_HTTP_MTOM
            ##SOAP12_HTTP
            ##SOAP12_HTTP_MTOM
            ##XML_HTTP

	   Other specifications could define tokens that start with ##
	   to alias new standard binding URIs that are introduced.
