  // Verify that invalid characters are stripped from the ID.
  $this->assertIdentical(backdrop_html_id('invalid-,./:@\\^`{Üidentifier'), 'invalid-identifier', 'Strip invalid characters.');

  // Verify Backdrop coding standards are enforced.
  $this->assertIdentical(backdrop_html_id('ID NAME_[1]'), 'id-name-1', 'Enforce Backdrop coding standards.');
