public function process($text, $langcode) {
  $restrictions = $this->getHtmlRestrictions();
  // Split the work into two parts. For filtering HTML tags out of the content
  // we rely on the well-tested Xss::filter() code. Since there is no '*' tag
  // that needs to be removed from the list.

  // After we've done tag filtering, we do attribute and attribute value
  // filtering as the second part.
