In many cases, the Asset (target) and Parties (assigner, assignee) are the same for multiple Permissions and Prohibitions in an ODRL Policy.
It maybe a useful change to support the Asset/Party at the Policy level, which means that these values all apply to the enclosed Perms/Prohibs (and conversely means that the Perms/Prohibs do not define these values).
