The CSsmSwpPolicyResolver is passed an swp value and uses this to create an swp policy 

frame that encapsulates the corresponding policy DLL

The swp policy is resolved using a map of swp values to policy file names.

The mapping of swp values to names is registered using the appropriate function.
