Subject is an instance of documentation is a kind of have axiom
AsymmetricRelation A BinaryRelation is asymmetric only if it is both an AntisymmetricRelation and an IrreflexiveRelationIrreflexiveRelation
(=>
    (instance ?REL IrreflexiveRelation)
    (forall (?INST)
       (not 
          (holds ?REL ?INST ?INST))))
TransitiveRelation A BinaryRelation ?REL is transitive if (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST3) imply (?REL ?INST1 ?INST3), for all ?INST1, ?INST2, and ?INST3BinaryRelation
(=>
    (instance ?REL TransitiveRelation)
    (forall (?INST1 ?INST2 ?INST3)
       (=>
          (and
             (holds ?REL ?INST1 ?INST2)
             (holds ?REL ?INST2 ?INST3))
          (holds ?REL ?INST1 ?INST3))))
crossesTransitiveRelation(crosses ?OBJ1 ?OBJ2) means that Object ?OBJ1 traverses Object ?OBJ2, without being connected to it 
(=>
    (traverses ?OBJ1 ?OBJ2)
    (or
       (crosses ?OBJ1 ?OBJ2)
       (penetrates ?OBJ1 ?OBJ2)))
