as its internal format. Thus I belived that transforming into SAX events
directly would be faster.

We use XSL at a part of a internet application so we output to a Writer
instead of a documentbuilder, but otherwise that shouldn't matter.

A naiive question, I'm sure, but ... what is the benefit of using the
transformer classes? Wouldn't it be faster to simply use XMLOutputter -->
Piped Output --> Piped Input --> DocumentBuilder?
