% Domain   : Semantic Web
% Problem  : Individual Enumeration Closed
% Version  : [Sch11] axioms.
% English  : If a class defines an enumeration class expression from two
%            individuals, and if an individual is an instance of the class but
%            is different from one of the two component individuals, then the
%            individual equals the remaining component individual.
