-   * However, for links enclosed in translatable text you should use t() and

-   *   - absolute: Whether to force the output to be an absolute link (beginning

-   *     such as in an RSS feed. Defaults to FALSE.
-   *   - attributes: An associative array of HTML attributes to apply to the
-   *     anchor tag. If element 'class' is included, it must be an array; 'title'
-   *     must be a string; other elements are more flexible, as they just need
-   *     to work as an argument for the constructor of the class
-   *     Drupal\Core\Template\Attribute($options['attributes']).

-   *     you will see the escaped HTML image tag. $text is not sanitized if
