This format, fitting the scope it was conceived for, does not model some of the characteristics that are needed for a dynamic simulation. More precisely, it cannot specify the following:
- The pose of the robot itself within a world.
- Joint loops (parallel linkages).
- Friction and other properties.
- Things that are not robots, such as lights, height maps, and so on.
