Summary of Actions in the WS-I Category
The WS-I category contains numerous actions from Basic Profile 1.1 and SSBP 1.0 that you can use to test a web service (of type Service or Virtual Service) for compliance with Web Service Interoperability (WS-I) standards.
Important:
A policy that contains WS-I actions must not contain any other type of action. If you need to execute other types of actions for the same event, you must place those actions in a separate policy.
