Please, those are the "standard" arguments against JSP, in the way
Cocoon uses XSP (like I explained in a previous mail) nobody will have
to edit an XSP page since it will be generated. And the logicsheet will
be written by developers, who know what they are doing.

Users just do stuff like

 <p>My quotes are <quotes/></p>

and there is no way they can screw up the logic.

Again, I totally understand you points of having a turing-complete
language expressed directly in XML, but that is just another stylesheet.
A very complex one, indeed, but that would allow us to work together. :)
