An uncommon data model concept is a child table with 2 foreign keys to the same table. For example, an employee might have a WorksForDeptNum, and an OnLoanDeptNum - both Foreign Keys to Department.

The system currently restricts this (with an appropriate error), so you cannot have sums/counts in such cases. The system presumes only 1, and throws a "TODO - disambiguate relationship" exception.

It should be possible to add a Sum/Count property child_role_name to designate the intended relationship.
