The result of history operation is a Bundle with type history containing the specified version history, sorted with newest versions first, and including deleted resources.
The request element provides information about the interaction that occurred and caused the new version of the resource.
Only operations create, update, and delete create history entries. Conditional creates, updates and deletes are converted to direct updates and deletes in a history list.
