Because forwarding delegates the production of the output to the target 
resource. But Cocoon expects the sitemap to produce something or an 
error is displayed.

So the only place where such forwarding is possible is in a Cocoon 
component that feeds the output with abitrary binary data, and Cocoon 
names it a reader ;-)

Andy, would you like to contribute a "ForwardReader", how ugly and 
servlet-tied as it may be ?
