<xsl:comment><![CDATA[[if lt IE 7]>
<link rel="stylesheet" href="iefix.css" type="text/css" media="screen" />
<![endif]]]></xsl:comment>
<xsl:comment>
end xhtml server ssi and client comments
</xsl:comment>
<!-- end XSL -->
<xsl:comment>
begin xhtml server ssi and client comments
</xsl:comment>
<xsl:comment><![CDATA[#include file="ssi.html"]]></xsl:comment>
