I meant to able to use embedded java to create
an instance of:
org.apache.cocoon.transformation.Transformer
Analogous to the way XSP currently works by
creating an instance of:
org.apache.cocoon.generation.Generator
(called XSPGenerator)
Now I see this is not supported, but what you have
suggested may help, thanks,
