enforcement (or "checking".) You can use the "on change
property" event to check the constraint whenever a
"StartTestCase" atom is renamed. One consequence of this choice
is that each atom must be given a unique name before the creation of the next,
since all are created with the same name ("StartTestCase").</span></span><span
