  foreach ($items as $delta => $item) {
    if (empty($item['sid'])) {
      continue;
    }
    $atom = scald_fetch($item['sid']);
    if (!isset($types[$atom->type]) || empty($types[$atom->type])) {
      $errors[$field['field_name']][$langcode][$delta][] = array(
        'error' => 'atom_reference_bad_type',
        'message' => t("Atom %title is of type %type, which can't be referenced in field %field", array(
          '%title' => $atom->title,
          '%type' => $atom->type,
          '%field' => $instance['label'],
        )),
