RE: Adding text to a transformed file

Two solutions for the price of one:

1. Supply the filename as a parameter to the stylesheet, and output the
extra message from within the stylesheet code, rather than trying to do
it from the calling Java code.

2. Create a FileOutputStream, write your message to it, then wrap the
same FileOutputStream in a StreamResult which you pass as the result
parameter to the transform() method.
