for-each-group in XSL 2.0

I have a simple code in XSL : If I use the standard for-each, works fine,
but when I use the for-each-group I receive an error... for-each-group must
not be used here...or something like that.

This is my XSL :

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/TR/WD-xsl"
language="JavaScript">
 
<!--<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
     version="2.0" language="JavaScript"> -->

 <xsl:template match="/">
 <div onClick="clickType(this);">
 <xsl:element name="SELECT MULTIPLE">
 
 <xsl:for-each-group select="xml/rs:data/z:row" group-by="@typeCode">
     
     <xsl:element name="OPTION">
     
      <xsl:value-of select="@typeName"/>
     
      <xsl:attribute name="VALUE">
      <xsl:value-of select="@typeCode"/>
     </xsl:attribute>
        
     </xsl:element>
   </xsl:for-each-group>
  </xsl:element>
 </div>
 
 </xsl:template>
</xsl:stylesheet>


In my html I also have changed the object dll

<script language="javascript"> 
   // Load XML 
  //var xmlDOC = new ActiveXObject("Microsoft.XMLDOM")
  var xmlDOC = new ActiveXObject("MSXML2.DOMDocument.3.0")
  xmlDOC.async= false
  xmlDOC.load("units.asp");
  window.alert(xmlDOC.documentElement.xml);
  
  // Load the XSL
  //var xslDOC = new ActiveXObject("Microsoft.XMLDOM")
  var xslDOC = new ActiveXObject("MSXML2.DOMDocument.3.0")
  xslDOC.async = false
  xslDOC.load("units.xsl")
  
  // Transform
  document.write(xmlDOC.transformNode(xslDOC))
  
  </script>

I receive my XML from a standard XML stream retrived by ADO (from my VB DLL)
The  XML stream:

<xml xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'

</xml> 

All that I've found in http://www.dpawson.co.uk/xsl/rev2/grouping.html did
not help me.

It seems to be simple...and I don't understant why it doesn't work.

Thanks in advance !
