  That is a possible decision for this group to take, but we are 
certainly able to decide to have language features relating to 
instances if we wish - and the charter doesn't rule that out. For 
example, the group could descide that
"owl:sameInstance" is something we wanted to add, and that would 
certainly be within scope.

again, seems to me Ian is pre-guessing a solution - he may well be 
right, but we're not constrained for this to be implemented as a 
special case.
