set a Node Parameter in the Transformer class

[Giraudet de Boudemange]

I have a problem with the setParameter method in the Transformer class 
of xalan.
I want to pass a Node parameter (a DOM element), but this node is always 
transform in
a String with the toString() method of the node.
Have a look to my code:
   String styleSheetURI= "AddToCatalog.xsl";

          TransformerFactory tFactory = TransformerFactory.newInstance();
          Transformer transformer =
              tFactory.newTransformer(new StreamSource(styleSheetURI));

          //PARAMETER
          DocumentBuilderFactory dFactory 
=DocumentBuilderFactory.newInstance();
          dFactory.setNamespaceAware(true);
          Document doc2 =dFactory.newDocumentBuilder().newDocument();
          Element node = 
doc2.createElementNS("http://example.com/auction/wsdl/doXslTransform","cd";); 

          node.appendChild(doc2.createTextNode("Text"));
          doc2.appendChild(node);
          transformer.setParameter("newCD", doc2.getDocumentElement());


          //SOURCE
          Document 
docSource=DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument(); 

          Element nodeSource=docSource.createElement("Catalog");
          docSource.appendChild(nodeSource);
          DOMSource source=new DOMSource( nodeSource);

          //RESULT
          DOMResult result=new DOMResult();


          //TRANSFORMATION
          transformer.transform(source, result);


Here is my styleSheet:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:transform version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:dxt="http://example.com/auction/wsdl/doXslTransform";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
>
<xsl:param name="newCD"><dxt:cd>DefaultText</dxt:cd></xsl:param>
<xsl:template match="/">
<xsl:element name="root">
 <xsl:copy-of select="$newCD"/>
</xsl:element>
</xsl:template>
</xsl:transform>

The result of the transform is:
<root>[cd: null]</root>

but I would like to have:
<root><cd><Text</cd></root>


If I don't set the parameter in the java program, the default value of 
newCD param is used, and the result is:
<root><dxt:cd 
xmlns:dxt="http://example.com/auction/wsdl/doXslTransform";>DefaultText</dxt:cd></root> 


So how can I do to pass my Node in parameter to the transformer?

Thanks
