Stefano,
I had the same idea a week ago. Damn I should be
louder ;)

Why not. It would be not very intelligent to ignore this option...

Definitly

I agree on that. But:
- which Xalan C++ libaries do you want to ship? All (Windows, Linux, Solaris....)?
- Leave it optional? The user can download the libary and we provide 
the interfaces and Xalan J is default... But then we have to abstract Xalan
in Cocoon, but that's clear (org.apache.cocoon.transform.*).
- Throw xalan J completly overboard? But then we arn't plattform independent
anymore (academic).
