% Domain   : Semantic Web
% Problem  : Class Complement Extensional
% Version  : [Sch11] axioms.
% English  : If a class is an equivalent class to the complement of another 
%            class, then the former class defines the complement of the other 
%            class. This test checks that class complement is realized as an 
%            iff-condition.
