Suggestion: Try an identity transform to get a copy of what the input 
stream looks like, and use that for debugging (or at least show it to us 
so we can help you debug).

I don't know whether the Cocoon SQLTransformer is related to the Xalan 
SQL extension. If it is, you may find that there are constraints on what 
kinds of stylesheets will work with it.
