     * - do have a Drupal route but have a custom scheme to simplify linking.

     *   resolves to the entity.node.canonical route with a node parameter of 1.)

     *   static files), use base: for the scheme to get a link relative to the
     *   Drupal base path (like the <base> HTML element). For a link to an entity
     *   you may use entity:{entity_type}/{entity_id} URIs. The internal: scheme

     *   - 'query': An array of query key/value-pairs (without any URL-encoding)
     *     to append to the URL.
     *   - 'fragment': A fragment identifier (named anchor) to append to the URL.
     *     Do not include the leading '#' character.
     *   - 'absolute': Defaults to FALSE. Whether to force the output to be an
     *     absolute link (beginning with http:). Useful for links that will be
     *     displayed outside the site, such as in an RSS feed.
     *   - 'attributes': An associative array of HTML attributes that will be
     *     added to the anchor tag if you use the \Drupal\Core\Link class to make
     *     the link.
     *   - 'language': An optional language object used to look up the alias
     *     for the URL. If $options['language'] is omitted, it defaults to the
     *     current language for the language type LanguageInterface::TYPE_URL.
     *   - 'https': Whether this URL should point to a secure location. If not
     *     defined, the current scheme is used, so the user stays on HTTP or HTTPS
     *     respectively. TRUE enforces HTTPS and FALSE enforces HTTP.

     *
     * Important note: the URI minus the scheme can NOT simply be validated by a
     * \Drupal\Core\Path\PathValidatorInterface implementation. The semantics of
     * the 'internal:' URI scheme are different:
     * - PathValidatorInterface accepts paths without a leading slash (e.g.
     *   'node/add') as well as 2 special paths: '<front>' and '<none>', which are
     *   mapped to the correspondingly named routes.
     * - 'internal:' URIs store paths with a leading slash that represents the
     *   root — i.e. the front page — (e.g. 'internal:/node/add'), and doesn't
     *   have any exceptions.
     *
     * To clarify, a few examples of path plus corresponding 'internal:' URI:
     * - 'node/add' -> 'internal:/node/add'
     * - 'node/add?foo=bar' -> 'internal:/node/add?foo=bar'
     * - 'node/add#kitten' -> 'internal:/node/add#kitten'
     * - '<front>' -> 'internal:/'
     * - '<front>foo=bar' -> 'internal:/?foo=bar'
     * - '<front>#kitten' -> 'internal:/#kitten'
     * - '<none>' -> 'internal:'
     * - '<none>foo=bar' -> 'internal:?foo=bar'
     * - '<none>#kitten' -> 'internal:#kitten'
     *
     * Therefore, when using a PathValidatorInterface to validate 'internal:'
     * URIs, we must map:
     * - 'internal:' (path component is '')  to the special '<none>' path
     * - 'internal:/' (path component is '/') to the special '<front>' path
     * - 'internal:/some-path' (path component is '/some-path') to 'some-path'
