Exactly the argument applies for Alberta, but this grid has higher codim
entities.

No, in this case we must have a default implementation, which is not
that difficult.

Very good. Then we are not far away from the higher codim entities,
because this is the most difficult part when providing higher codim
entities.

Ok.
