embedded xslt in Internet Explorer 6.xx /W2K

Can someone tell why the following xml file  renders the string "test"
in Mozilla but only the string "elementContents" in IE 6.xx?

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet href="#xslstyle"  type="text/xsl"?>
<!DOCTYPE test [
<!ATTLIST xsl:stylesheet id ID #REQUIRED>
]>
<test>
  <xsl:stylesheet id="xslstyle"
                  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                  version="1.0">
    <xsl:template match="test">
      <p><xsl:value-of select="local-name()"/></p>
    </xsl:template>
  </xsl:stylesheet>
  <element>elementContents</element>
</test>

Could it help to use WD-XSL to enable embedded stylesheet
processing in IE6.xx /W2K?

Does it work in WXP or will it work in Longhorn which is
supposed to intergrate msxml6.0?
