[xsl] Using variables in extension elements

[Roger I Martin PhD <hypernexdev@xxxxxxxxxxxxxxx>]

Hi folks,

   <xsl:variable name="parameter-list">
           <xsl:for-each 
select="../*[position()&gt;1]"><xsl:call-template name="set-argument">
                   <xsl:with-param name="current-variable">
                   <xsl:apply-templates select="." mode="parameter">
                   <xsl:with-param name="argument" select="true"/>
                   </xsl:apply-templates>
                   </xsl:with-param>
                   <xsl:with-param name="current-type" 
select="translate(@type,' ','')"/>
               </xsl:call-template><xsl:if 
test="position()&lt;last()"><xsl:text>, </xsl:text></xsl:if>
           </xsl:for-each>
       </xsl:variable>
       <mathmlx:put key="type-parameter-list" value="$parameter-list"/>

....
   public void put(org.apache.xalan.extensions.XSLProcessorContext context,
              org.apache.xalan.templates.ElemExtensionCall extElem) 
throws javax.xml.transform.TransformerException
   {
       String key = extElem.getAttribute("key");
       String value = extElem.getAttribute("value");
       if(value.startsWith("$"))
       {
           ;
           //extElem.
           org.apache.xml.utils.QName qname=new 
org.apache.xml.utils.QName(value.substring(1));
           //qname.
           org.apache.xpath.VariableStack 
vs=context.getTransformer().getXPathContext().getVarStack();
           for(int i=0;i<vs.size();i++)
           {
               //vs
               System.out.println(vs.elementAt(i));
           }
           
value=vs.getVariableOrParam(context.getTransformer().getXPathContext(), 
qname).toString();
           System.out.println(value+" "+value.substring(1)+" "+value);
           //value=extElem.getAttribute(value.substring(1));
       }
       table.put(key, value);
   }
  
Trying to use the getVariableOrParam function to get the value of the 
variable to store for global use.  Keep getting not resolvable.  QName 
construction too simplistic?  Name space issue?  The for loop shows the 
last element has the value of 'parameter-list' so a suspect it is there.

Curiousity question: is anyone extending toward xslt 2.0 and xpath 2.0?
