% Domain   : Semantic Web
% Problem  : Reflexive Property Extensional
% Version  : [Sch11] axioms.
% English  : If the extension of a property is reflexive, then the property
%            itself is. Note that reflexivity is globally defined on the whole
%            universe, which has infinite cardinality under the RDF-Based
%            Semantics. Therefore, instead of explicitly defining the
%            extension of some custom property, the extension of the built-in
%            property owl:topObjectProperty is referred to.
