setParameter() does not work when using transformation chaining

           Summary: setParameter() does not work when using transformation
                    chaining
           Product: XalanJ2
           Version: 2.4Dx
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xalan.transformer
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: robbie.ceulemans@kbc.be


When using transformation chaining, the setParameter()-method does not work. 
The parameter is not passed to the stylesheet. When just using a normal 
transformation (not chaining) it works fine. The difference is that for 
chaining, the TransformerIdentityImpl is used instead of the TransformerImpl. 
In the TransformerIdentityImpl, the parameter is just put in a Hashtable and 
nothing is done with it afterwards.

example:
SAXTransformerFactory stf = (SAXTransformerFactory)
TransformerFactory.newInstance();
XMLFilter filter = stf.newXMLFilter(new StreamSource("test.xslt"));
StreamResult sr = new StreamResult(System.out);
Transformer transformer = stf.newTransformer();
SAXSource transformSource = new SAXSource(filter, new InputSource
("test.xml"));

transformer.setParameter("testParam", "value");
transformer.transform(transformSource, sr);

I made it work by hacking into Xalan:
- add a getter method in the TrAXFilter class for the m_transformer field.
- after creating an XMLFilter from the SAXTransformerFactory, do the
following:
Transformer transformer = ((TrAXFilter)filter).getTransformer();
transformer.setParameter("testParam", "value");
