In order to satisfy the requirements of a history Bundle (specifically bdl-3 and bdl-4), note that Bundle.entry.request must exist.
For the status resource (entry[0]), the request is filled out to match a request to the $status operation.
Since this is an error notification and does not include additional entries, no additional constraints are imposed by Bundle requirements.
