This class is not intended to be used directly, but only for serving as the domain of 'implements' and similar relations. The disjointness axiom serves to block iterated chains of 'implements', etc., relationships.
A 'specified' entity is typically an individual that represents the asset as designed, with restrictions that capture requirements.
A 'specified' individual may be matched with an individual representing an 'actual' individual. Naming for the according relations may include: 'installed as' for physical objects, and 'executed as' for activities.
