The current wording in [11.4.5 Delete an Entity](http://docs.oasis-open.org/odata/odata/v4.01/os/part1-protocol/odata-v4.01-os-part1-protocol.html#sec_DeleteanEntity) in [Protocol] states:
On successful completion of the delete, the response MUST be 204 No Content and contain an empty body.
This is overly restrictive. HTTP allows Delete to return a response, and since we added a preference header for clients to request a response from requests that typically may not return responses, we should allow clients to request, and services to return, responses from DELETE (i.e., if return=representation preference is specified).
The response should be a representation of the deleted entity.
