31: * This class performs an epistemic remove of axioms described by the axiom
32: * descriptor. </p>
33: * <p/>
34: * Epistemic remove means that only information known to the application is
35: * deleted. The assertions in the descriptor represent this information. Thus,
36: * only these assertions are removed from the ontology. Note that if the
37: * descriptor contains an unspecified property assertion, all property
38: * assertions related to the subject individual are removed from the property's
39: * context.
