Source	What it shows
model#constraint-asset	Example Use Case: The Policy defines a target source http://example.com/media-catalogue that is an AssetCollection of multimedia videos. The target also has a refinement that specifies the characteristics of the AssetCollection members. In this case, the target subset of Assets will be those that have a running time of less than 60 minutes, and each of those may be played. Note that the runningTime leftOperand is defined in the ODRL Profile http://example.com/odrl:profile:11 together with the play action.
