This structure represents the unique key fields associated with identifying a Resource. Resourcess can be identified by ResourceDisplayName, ResourceReferenceSystemId or ResourceUid. When specifying a PwsResourceRef as an input to a web service, you may specify one or all three fields the ResourceDisplayName, ResourceReferenceSystemId and/or ResourceUid. However, if you do specify all three, they must refer to the same Resource or the Resource reference will not be considered valid. When a PwsResourceRef is returned in the response to a web service, the ResourceDisplayName, ResourceReferenceSystemId or ResourceUid will be populated, and guaranteed to refer to a single Resource.
