Please consider correcting the predicate part of the InterfaceParent schema. As
things stand, interfaceFaultComps is unconstrained if interfaceOpComps is an
empty set in a given ComponentModel2, i.e., the predicate part could be
simplified to true. Likewise, interfaceOpComps is unconstrained if
interfaceFaultComps is an empty set.

Correction is straightforward: each constraint should be expressed in a
separate universal quantification.

Yours sincerely,

Mark
