2.2.4.1 SOAP Action String

A SOAP Action string is a URI that is used as the SOAP Action field in the HTTP header as specified in [SOAP1.1] section 6. The SOAP action is derived from the Remote Method. An implementation MUST define its own mechanism to create a SOAP action for the given Remote Method. The client and server MUST agree on the mechanism so that a given Remote Method ends up with the same SOAP action on both sides.<25>
