Example Use Case: The assigner of a target Asset http://example.com/photoAlbum:55 expresses an Agreement Policy with both a Permission and a Prohibition. The assigner Party http://example.com/MyPix:55 assigns the Permission display to the assignee Party http://example.com/assignee:55 at the same time a Prohibition to archive the target Asset. Additionally, in case of any conflicts in the Policy (e.g., between Permissions and Prohibitions), the conflict property of the Policy is set to perm indicating that the Permissions will take precedence.
