There is a Transformer (currently broken :-( ) in the scratchpad that tried
to do something along these lines. It worked in an early Cocoon Alpha
release, and quick attempts to have it working again weren't sufficient.
Look at Chart2SvgTransformer.java in scratchpad.
It's there waiting for:
1 someone to fix it
2 someone to write something better
Which means.... that I can't wait to use your Transformer instead! :-)
