I wonder what is wrong with this text from RFC2616 [1]

The DELETE method requests that the origin server delete the resource
identified by the Request-URI. This method MAY be overridden by human
intervention (or other means) on the origin server. The client cannot be
guaranteed that the operation has been carried out, even if the status code
returned from the origin server indicates that the action has been
completed successfully. However, the server SHOULD NOT indicate success
unless, at the time the response is given, it intends to delete the
resource or move it to an inaccessible location.

A successful response SHOULD be 200 (OK) if the response includes an entity
describing the status, 202 (Accepted) if the action has not yet been
enacted, or 204 (No Content) if the action has been enacted but the
response does not include an entity.

I can't think what issue there is and what needs to be clarified.
