Causes changes in the RecordingScope to be rolled back if the scope execution is not successful. In case of declarative scope (RecordingScopeAttribute), it means that changes done by the method will be rolled back if the method results in an exception. For imperative scopes (OpenScope(RecordingScopeOption), the changes will be rolled back if the scope is disposed by the Dispose() method without previous call to the Complete() method. Unlike normal scopes, atomic scopes are nested. However, only the top scope can be seen in the UndoOperations and RedoOperations collections.
