XSLT in Firefox and IE6.0

I was trying to get my xsl file to work in Firefox, which I did, but
now it seems it doesn't work at all in IE6.0.  I thought 6.0 used the
same standard as Firefox?

below is the js used to load the page:

	<script type="text/javascript">
		var isIE;
		var isNav;
			isIE = (navigator.appName == "Microsoft Internet Explorer");
			isNav = (navigator.appName == "Netscape");

			if (isIE)
			{
				// Load XML
				var xml = new ActiveXObject("Microsoft.XMLDOM")
				xml.async = false
				xml.load("StatsReport_allstats.xml")

				// Load XSL
				var xsl = new ActiveXObject("Microsoft.XMLDOM")
				xsl.async = false
				xsl.load("NodeStats2.xsl")

				// Transform
				document.write(xml.transformNode(xsl))
			}
			if (isNav)
			{
				//for mozilla/netscape
				var processor = new XSLTProcessor();
				var xslt = document.implementation.createDocument("", "", null);
				xslt.async = false;
				xslt.load("NodeStats2.xsl");
				processor.importStylesheet(xslt);

				var src_doc = document.implementation.createDocument("","", null);
				src_doc.async = false;
				src_doc.load("StatsReport_allstats.xml");
				var result = processor.transformToDocument(src_doc);
				var xmls = new XMLSerializer();
				var output = xmls.serializeToString(result);
				document.write(output);
				alert("done");
			}

	</script>


I stuck a few alerts into the IE code, so I know the transform is
what's failing.
This is my stylesheet tag in my xsl:
<xsl:stylesheet version="1.0"
				xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:ns1="schema:StatsReportSchema.xml">

6.0 sp2 would load fine with the working draft:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/TR/WD-xsl">

To have this work in both IE and Firefox do I have to duplicate my code
for both versions of xsl (that would be the only workaround I can think
of)?  It still seems like really this ought to work for both, if they
both support the same versions.  Do I need an IE update?  Or is there
no way to have the same xsl stuff work for both and I really do just
need to duplicate everything for both browsers?
