The right thing to do is writing your own function which returns this 
attributes as an associative array and then use <tal:attributes>.
You may also use fallback to php:
http://phptal.org/manual/en/split/tales-php.html

The best choice is to write custom pre-filter, which adds those 
attributes automatically where needed.

Here is the function for reference:

1696  /**
1697   * Display the language attributes for the html tag.
1698   *
1699   * Builds up a set of html attributes containing the text 
direction and language
1700   * information for the page.
1701   *
1702   * @since 2.1.0
1703   *
1704   * @param string $doctype The type of html document (xhtml|html).
1705   */
1706  function language_attributes($doctype = 'html') {
1707      $attributes = array();
1708      $output = '';
1709
1710      if ( $dir = get_bloginfo('text_direction') )
1711          $attributes[] = "dir=\"$dir\"";
1712
1713      if ( $lang = get_bloginfo('language') ) {
1714          if ( get_option('html_type') == 'text/html' || $doctype == 
'html' )
1715              $attributes[] = "lang=\"$lang\"";
1716
1717          if ( get_option('html_type') != 'text/html' || $doctype == 
'xhtml' )
1718              $attributes[] = "xml:lang=\"$lang\"";
1719      }
1720
1721      $output = implode(' ', $attributes);
1722      $output = apply_filters('language_attributes', $output);
1723      echo $output;
1724  }
