RE: Grouping over multiple files

>         <xsl:param    name="node" as="node()"/>
>         <xsl:variable name="root" as="node()"
>                       select="root($node)"/>
>         <xsl:choose>
>           <xsl:when test="$root = $north">
>             <xsl:text>north</xsl:text>
>           </xsl:when>
>           <xsl:when test="$root = $south">
