parameter of :func:`add_wall_representation`.
.. warning::
The ``normal`` points toward the **removed** material (the discarded
side), not toward the kept material. For a slope clip the normal
points upward into the removed wedge above the slope line. For a
side mitre the normal points outward away from the wall body.
After clipping, set the parent ``IfcShapeRepresentation``
``RepresentationType`` to ``"Clipping"``.
