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.
For additional entries, the request SHOULD be filled out in a way that makes sense given the subscription (e.g., a POST or PUT operation on the resource).  However, a server MAY choose to simply include a GET to the relevant resource instead.
