Protection Assertions
Use protection assertions to identify the parts or elements of a SOAP message that are protected and to specify the level of protection to provide. There are two basic types:
Integrity assertions that define the parts or elements of the message that should be signed.
Confidentiality assertions that define the parts or elements of message to encrypt.
Important:
If you are implementing WS-SecurityPolicy 1.2 standards, the sp prefix in the assertions described below represents this namespace: http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702. If you are implementing WS-SecurityPolicy 1.1 standards, the sp prefix represents this namespace: http://schemas.xmlsoap.org/ws/2005/07/securitypolicy.
