WS-Policy

WS-Policy defines a general-purpose XML-based model and syntax that may be used to describe and communicate the policies that inhere to any Web-based service. In other words, WS-Policy assertions express the capabilities and constraints that apply to some particular Web service to which they pertain.

More specifically, WS-Policy delivers a flexible, extensible grammar for assertions regarding the capabilities, requirements, and general characteristics in a specific XML Web services based system. WS-Policy allows such properties to be stated as policies, which may be simple declarative assertions but may also be more complex conditional declarations. In this context, a policy consists of one or more policy assertions and may include such things as authentication schemes, transport protocol selection, privacy policy, QoS characteristics, and more.
