There's no indication in the stack trace that this problem might have anything to do with Saxon. Saxon is writing the transformation result to a ContentHandler that is part of JAXB code, and the JAXB code has raised an exception. Not knowing JAXB at all well, I've no idea why it's failing.
 
BTW: the purchase page for the pro and enterprise editions is unusable (http://www.saxonica.com/erol/erol.html gives me a blank page in both Firefox 3.5 and IE 7) 
 
It looks OK to me at the moment, though still showing the old product list. But the people who look after it for Saxonica are working on an upgrade (both of the shop software and the Saxon product list) and you might have caught it at a bad moment. Sorry about that.
