  $fr_info = title_field_replacement_info($entity_type);

    // We copy (rather than reference) the values from $form_state because the
    // subsequent call to drupal_array_get_nested_value() is destructive and
    // will affect other hooks relying on data in $form_state. At the end, we
    // copy any modified value back into the $form_state array using
    // drupal_array_set_nested_value().
