Premise
John child John .

Conclusion
John rdf:type _:1 .
_:1 rdf:type daml:Restriction .
_:1 rdf:onProperty child .
_:1 rdf:hasClass :_1 .


Intermediate step A.

John rdf:type _:2 .

_:1 rdf:type daml:Restriction .
_:1 rdf:onProperty child .
_:1 rdf:hasClass _:one .
_:one rdf:type daml:Class .
_:one daml:oneOf _:list .
_:list rdf:type daml:List .
_:list daml:first John .
_:list daml:rest daml:nil .

(This follows from two explicit comprehension axioms).

Intermediate step B.

John rdf:type _:one .

Then the conclusion follows by deleting triples.
