  // still access $form_state['field'][$field_name] directly,
  // - top-level fields (empty $parents) are placed directly under
  //   $form_state['fields'][$field_name].
  // - Other fields are placed under
  //   $form_state['field']['#parents'][...$parents...]['#fields'][$field_name]
  //   to avoid clashes between field names and $parents parts.
  // @todo Remove backwards compatibility and use a unique
  // $form_state['field'][...$parents...]['#fields'][$field_name] structure.
