[Swoop] Mutually Disjoint Classes?

[Kolovski, Vladimir]

Chris, Chi, 
 There's a proposal to include another construct in OWL which will allow for specifying that all classes in a set are pair-wise disjount:

 DisjointClasses(class1 class2  classn)

It should be part of OWL 1.1. More info here:

or

I don't know how this would be done, but I agree it would extremely  
useful. In fact I think it would be great if there was a way to state  
than an entire ontology satisfied the pairwise disjoint criteria. I  
guess this could be done at the interface level and compiled into  
some pretty verbose owl - would there be a cleaner way?
