Web Services Policy Framework (WS-Policy) provides a general purpose model and corresponding syntax to describe and communicate the policies of a Web
Service. WS-Policy defines a base set of constructs that can be used and extended by other Web Services specifications to describe a broad range of service requirements, preferences, and capabilities.
WS-PolicyAssertions specifies a set of common message policy assertions that can be specified within a policy.
WS-PolicyAttachment specifies three specific attachment mechanisms for using policy expressions with existing XML Web
