It allows a discussion of structural properties of quantum field theory as well as the perturbative construction of renormalized interacting models on generic curved backgrounds and opens in principle the way towards a background independent perturbative quantization of gravity.to appear in the Proceedings of the International Conference on Mathematical Physics, Lisbon 2003High Energy Physics - Theorytext
