    // Because the renderer is designed for HTML rendering, it filters
    // #markup for XSS unless it is already known to be safe, but that filter
    // only works for HTML. Therefore, we mark the contents as safe to bypass
    // the filter. So long as we are returning this in a non-HTML response
    // (checked above), this is safe, because an XSS attack only works when
    // executed by an HTML agent.
    // @todo Decide how to support non-HTML in the render API in
    //   https://www.drupal.org/node/2501313.
