If selected, it will be checked, whether cycles in sub-type relationships exists now at the involved types.
Types which internally manage their sub-type relationships themselves usually don't check for cycles,
since there might be already (other) cycles by user-defined types (e.g. classes with sub-super classes) and which are reported with dedicated validations.
