     *   changing the whole array. For example the 'sub_process' and the 'flatten'
     *   plugins. If the plugin only needs to change a single value, then it can
     *   skip setting this attribute and let
     *   \Drupal\migrate\MigrateExecutable::processRow() handle the iteration.
     * @param class-string|null $deriver
     *   (optional) The deriver class.
