The Service Policy Manager provides several predefined policy types and two predefined value special requesters: ALL and unauthenticated.
A policy type associates validation logic with a policy attribute. The validation logic decides the contents which are allowed as the associated attribute value.
In the Service Policy Manager, policy types serve to validate only the form of the value contents, not the semantics. Semantics are intended to be interpreted by the services that use those policy attributes. In implementation, the form factor will be enforced through the regular expressions that validate the content of the policy value string. This can be used to enforce basic types such as integers and floats, as well as more complex strings such as URIs.
The Service Policy Manager provides one predefined special operation ALL which is synonymous with all operations.
You can specify the operation as ALL to create default operation policies, which Service Policy Manager will apply to all existing and future operations within the service.
