Yes! This is the correct interpretation. Usman, please do it like suggested by Simon. So, we keep the duplicates in MSE. Ok I'll change VerveineSharp to implement this interpretation. But I do not understand what is mean by direct and indirect references because as I understand the meta-model provides only one type i.e. a Reference class to instantiate references. How do we do the different between direct and indirect?
