Hi,
I'm using P4 b108 and I created an OWL 1 ontology, with a set of
disjoint (sub)classes. I discovered that if you manually specify class'
disjointness, then the axioms are saved (in RDF/XML) as OWL 1 with
owl:disjointWith axioms, whereas if you use the shortcut C-j (or the
menu item Edit -> make all siblings disjoint), they are saved with the
constructors owl:AllDisjointClasses and owl:members, therefore breaking
compatibility with OWL 1.

As a side note, the OWL Validator at mygrid.org.uk is not working today,
so I cannot check against it (but I did it a couple of days ago).

So, I wonder whether there is the possibility to save the ontology in
OWL 1, using only owl:disjointWith.

Thank you in advance,
Stefano David
