  // returned. Also set returnedItem to indicate that no new item was returned.
  //
  // Otherwise, this in a "special" UpdateItem operation, such as a recurring
  // task marked as complete (the returned item in that case is the one-off
  // task that represents the completed instance).
  //
  // Note that there can be no returned item at all, as in an UpdateItem call
  // with MessageDisposition set to SendOnly or SendAndSaveCopy.
