...Now things can be different, however, for implementations that use the same high-level concepts (a flow engine or a ServerPages generator) but a different approach, such as flow engines driven by an existing back-end...
wow - Flow engines driven by external back-ends....this opens up a whole new set of (realistic and useful) possibilites.
.... But these ones will be application-specific and won't be present in Cocoon's CVS. But the important point is that Cocoon should not prevent them to exist where needed....
Yes! Interfaces, it's all about interfaces.
Having a clean abstract interface to the Flow engine will be a Good Thing, thanks Sylvain and Marc for your analysis!
