This also applies if you do one of the following:

  • You delete a class defined as subclass, so the respective parent class has to be deleted first.

  • You delete a class that is defined as domain or range for a relation or attribute.

  • You delete a relation or attribute defined as subproperty, in that case the respective parent property has to be deleted first.
