To add to what David posted ask the customer what he or she intends to do. It the customer application passes in the 'real' user then the customer may be trying to capute who really performed a change or may actually want to use the dbms_rls package.
Personally I do not think customers should have the ability to create objects in a production environment. If this is a valid activity for the application then I would want the object creation handled via a package referenced via a provided screen interface.
