Problem with Transformer.setParameter() in SAX chain.

[Edward L. Knoll]

I have chain of Sax handlers which is effectively a XMLReader chained to 
SAXTransformer chained to a custom ContentHandler chained to a 
Serializer.   I am actually parsing multiple XML input streams to 
generate a single output XML stream.   The custom Content Handler 
suppresses all but the first startDocument() event and the last 
endDocument() event to keep the Serializer which is generating the 
single XML output from getting upset.

This is the net chain; my actually chain contains some custom "tee" 
ContentHandlers and additional flows of SAX events, but I don't believe 
those to be germane to my problem.

I need to change a parameter with the SAXTransformer for each file 
processed.  This parameter is used to generate an output element for 
each file processed. I can do a setParameter() followed by a 
getParameter() and see that the parameter is changed in the Transformer. 
  This is done for each file before doing a XMLReader.parse().

My problem is that the elements in the output XML which represent this 
changing parameter only have the last value this parameter was set to. 
I've tried doing a Transformer.clearParameters() between 
XMLReader.parse() actions, but that appears to have no affect.

I would think that each XMLReader.parse() execution and so each XSL 
Transformation would be independent of each other.  I don't see how 
anything other than the value of this changing parameter can be 
propagating through the custom ContentHandler given the signatures of 
the ContentHandler methods.
