Define Stereotype Constraints

If you need to define the conditions and rules under which the Stereotype element operates and exists, you can do this by setting Constraints on the element. Typical constraints are pre- and post- conditions, which indicate things that must be true before the element is created or accessed and things that must be true after the element is destroyed or its action is complete.

You can show the constraints for an element directly on the diagram, using the 'Compartment Visibility' function.
