Would it be feasible to think about XSLT support?
The reason I am saying that is not that JavaScript or Scheme are scary or
but having lead projects with mixed support for Java, C++, SQL, PL/SQL and
I found it quite mind boggling to switch back and forth between development
debuggers and language syntaxes.
It's an usability and productivity point I am trying to make, nothing else.

I would be interested, since we need a more sophisticated example for Form
handling as well.
Our current scenario is a multi page wizard which collects information about
the user and sends it to the
(non existing yet) Cocoon registration feedback archive. Would that be

Is there a draft in CVS?

I'm all ears.

Whoop, a third ear pops out.
