Compound traffic objects

For traffic objects it must be possible to generate compounds of objects, e.g. a truck towing a trailer, a car towing a trailer, a person pushing a wheelchair with a person on it, a person pushing a bike, a person riding a bike. Domain Model and Language Group need to decide how this is modelled and expressed in the language. In the DM meeting on March 8th it was decided, that LC prepares examples for a discussion basis.
