I had a quick look at your XalanTranformer, and I kind of disagree the way
you're using DOM to load the StyleSheet document. 
Why don't you use the trax.TemplatesBuilder which purpose is precisely to
build a cleaner-lighweight-internal Object model from a SAX2 XMLReader ?

So instead of writing (starting at line 85 of XalanTransformer.java) :
			
			DocumentBuilderFactory dfactory =
DocumentBuilderFactory.newInstance();
			DocumentBuilder docBuilder =
dfactory.newDocumentBuilder();
			org.w3c.dom.Document outNode =
docBuilder.newDocument();
			InputSource xslsrc =
resolver.resolveEntity(null,xsluri);
			org.w3c.dom.Node doc = docBuilder.parse(xslsrc);
			trax.Templates templates =
processor.processFromNode(doc);
			transformer = templates.newTransformer();

You should write :
			
			XMLREader reader =
XMLReaderFactory.createXMLReader();
			trax.TemplatesBuilder templatesBuilder =
processor.getTemplatesBuilder();
			reader.setContentHandler (templatesBuilder);
			reader.parse(resolver.resolveEntity(null,xsluri));
			trax.Templates templates =
templatesBuilder.getTemplates();
			trax.Transformer transformer =
templates.newTransformer();
			
And so on.

This approach would allow you to set the templates object in the 'store'
component, and every new request will make a call to the method
templates.newTransformer() since the 'templates' instance is thread safe
from spec.

All the best,

Sebastien
