Math relationships between analytical shapes

Does Collada, without using extra elements, support math relationships between analytical shapes?

For instance if one has a box and a tapered_cylinder and wishes to put the tapered_cylinder inside the box and subtract it so that there is a cylinder hole in the box. Can Collada 1.5.0 support this? I am interested in Analytical shapes only and not meshes.

Certainly you can position the two shapes as you describe, one inside the other.

The <shape> has a <hollow> flag that you could use as a hint to do the CSG calculation. I think you would need some <extra> meta data to define the algebra though; either on the <rigid_body>, <shape> or the <physics_material> depending on your approach.
