Standard RIF must support normative rules

Full Statement

Standard RIF must be able to express normative rules. An example of such a rule is An EU-Rent customer can rent at most one car at a time, which defines restrictions within the business of the car rental company EU-Rent. Normative rules are also called structural rules in the business rules community and integrity constraints in the database community.
