  '#default_value' => array(
    'url' => 'admin/content',
    'title' => 'List of content',
    'attributes' => array( // These are extra elements (see flags below)
      'title' => 'A link to Content', // Prepopulates the "title" attribute.
      'class' => 'additional-css-class',
      'target' => '_blank',
    ),
  ),
