either is - dropping is easier.

I was intending to do this tomorrow morning - with both syntaxes (as 
suggested by Peter and Pat), but probably limited to only min or max.

Yes - but isn't producing an OWL Full semantics achieved by doing all 
these implementation details.

I think that is the task. And QCRs are as good a place to start as any 
other. Getting one or two of these items done, might then give us enough 
idea of where we might be going to have an informed discussion.

I would think subproperty chains were fairly important, with some of the 
things as more minor.

What is your sense of what the major issues are, that are not reducible 
to a collection of implementation details?

Bijan's alternative proposal is probably one ...
I think whether we wish to revisit the layering issues is another (and 
this say interacts with Bijan's skolemization proposal).
