Not Really XSP
Ugo points out that there’s a different “XSP” that has absolutely nothing to do with Cocoon:
XSP technology is a revolutionary innovation from Trilog built to improve both the development and execution of powerful Web applications. As the core technology in FlowBuilder XML Edition, XML Server Pages (XSPs) provide the framework to create dynamic applications that leverage reusable components in a manner that is faster, more intuitive, more flexible, and more easily maintained than JSPs or ASPs.
