Constraint Types

In an element 'Properties' definition, each constraint on the element is defined by type in the 'Constraint' field. You can select the appropriate value from a drop-down list, which initially contains the system values:

Invariant
Post-condition
Pre-condition
Process and
OCL

You can add to or replace any of these values with your own custom values.
