I see no problem expressing these owl-entailments simply by reusing what the RDF
Core tests have done.

There is no N3 anywhere there.

e.g.

The premises are put in one file, the conclusions in another, and in the
"Manifest" file the implication is expressed:

from
http://www.w3.org/2000/10/rdf-tests/rdfcore/Manifest.rdf

<test:NegativeEntailmentTest

To use this for a Negative owl entailment we would need to change the pointers
to various documents (the premises, the discussion etc); change the pointer
concerning the set of entailment rules from pointing to the RDF space to
pointing to the OWL space.

It's not perfect, but its sufficient.
We can always add a property or two if necessary.
