Add a canonical link to all pages, so search engines will prefer 2.2 over 2.0

           rel="stylesheet"

           href="{$path}/style/css/manual-print.css"/>

    <!-- chm files do not need a favicon -->

    <!-- chm files do not need a favicon or a canonical link-->

    <xsl:if test="not($is-chm or $is-zip)">&lf;

        <link rel="shortcut icon" href="{$path}/images/favicon.ico" />

        <link rel="canonical" href="http://httpd.apache.org/docs/2.2{concat($metafile/path, $metafile/basename, '.html')}"/>

    </xsl:if>

</head>
