  // The above workaround however generates an incorrect path when the site is
  // located in a subdirectory, which is why the following logic adds the base
  // path of the installation.
  // See https://www.drupal.org/project/simple_sitemap/issues/3154494.
  // All of this seems to be an over engineered way of writing 'sitemap.xsl',
  // but may be useful in cases where another module alters the routes.
