This tracing feature is intended for developers who are debugging 
optimizer problems. I don't believe it should ever be exposed as a 
supported feature or used in the Derby tests. There may still be 
reasons for creating an XML format, but I would prefer not to put 
hurdles in the way of creating simple development tools.
