Well, here's the thing. you can do this, but still can't modify that
output. So you still can't do the equivalent of servlet chaining, which
is what it seems that you are getting at. Besides, for Cocoon in
particular, this really goes against the whole model used. We are going
to have to really think things through as to how to handle this sort of
thing. That's why I am taking lots of time to add Cocoon support - I
could easily make a producer version of Turbine, but I'm not sure that
splintering development for every "version" of Turbine is the right
idea.

I'm not sure we want to do this - Turbine is an _application_ framework,
and trying to add servlet level tasks makes me nervous... I think we may
ahve to think long and hard about how we architect the "future" of
Turbine. This is serious revision time, but we may need to do it. I'll
come up with an idea and some code...

Right, this is really bad... a slippery slope.

-0 for now because I don't have a solution, -1 as soon as I have one.
