probe class

A class that is added to an ontology for the sole purpose of checking the consistency of an ontology. For example, an ontology author may add a probe class for testing purposes that is deliberately meant to be inconsistent. The author might prefix the class name with "Probe" in order to help other authors understand that it is deliberately meant to be inconsistent; for example: ProbeInconsistentTopping (as a class name in a Pizza ontology).
