2.1 Transport

The SOAP over WebSocket Protocol Binding requires the WebSocket transport protocol (as specified in [RFC6455])<1>.

A service endpoint that uses the SOAP over WebSocket Protocol Binding with SOAP 1.2 [SOAP1.2-1/2007] MUST set the value of the transport attribute of the wsoap12:binding element [WSDLSOAP] to http://schemas.microsoft.com/soap/websocket.
