It is a building block that is used together with other Web services and application-specific protocols to accommodate a wide variety of policy exchange models. WS-Policy is currently used in Web services projects such as Axis2, Sandesha2 and WSS4J to process policy information they require. The framework facilitates the automation of exchanging configuration information between Web services infrastructures to ensure interoperability of both client and server.
