Last change on this file since 1506 was 1506, checked in by bnemhaus, 4 years ago

Permissions for encrypting frames are now respected. (Group level permissions still need testing and maybe implementation)

The current implementation of Hetrogeneous Owner requires that the owner of the frame specify the available labels. Injecting the property "HetrogeneousEncryptionLabels: <label name>" into the frame name item adds the specified label to the list of labels that those with 'Hetrogeneous (Owner)' permission are able to use.
