My experience of xUML (actually its predecessor, and from a competitor at that) was that you ended up doing quite a lot of design, and even programming -- just not in Ada. > We hope to apply that to automotive systems soon - measuring > footprint, real-time performance and so on.

Presumably for any really interesting SPARK annotations you'd have to decorate the model? The model compiler can make deductions from the model but I would have expected them to be about modelling (eg multiplicities), not so much about automotive systems.
