I've changed the Authorization section of FEP-c7d3 (Ownership). Now activity and its object/target can have different owners as long as they have the same origin.

For example, this allows admins and moderators to Delete objects and Remove objects from collections hosted on their server.

Same origin principle equally applies to FEP-ef61 portable objects where naming authority of URI is not a DNS name but a DID.
