WS-Policy provides a general purpose model and syntax to describe and communicate the policies of a Web service.

The Web Services Policy Framework (WS-Policy) specification defines an abstract model and an XML-based expression grammar for policies. This specification, Web Services Policy Attachment (WS-PolicyAttachment), defines two general-purpose mechanisms for associating such policies with the subjects to which they apply. This specification also defines how these general-purpose mechanisms can be used to associate WS-Policy with WSDL and UDDI descriptions.
