• #title: The link text to pass as argument to Drupal::l().
• One of the following:
  • #route_name and (optionally) a #route_parameters array; The route name and route parameters which will be passed into the link generator.
  • #href: The system path or URL to pass as argument to Drupal::l().
• #options: (optional) An array of options to pass to Drupal::l() or the link generator.
