Yes, the documentation is wrong.  Here's a version
that I _think_ will work:

    function MarkupExcerpt($pagename) {
      $page = RetrieveAuthPage($pagename, 'read', false);
      return substr(@$page['text'], 0, 200);
    }

    $FmtPV['$MarkupExcerpt'] = 'MarkupExcerpt($pn)';
    $FeedFmt['rss']['item']['description'] = '$MarkupExcerpt';
