Jos, that is in the subset of the semantics where I think there could  
or should be harmonization.

If you note the example of the "semantic" divergence (which isn't  
really a difference in semantics but in the available operators...but  
presumably predicates and operators are very user visible aspects of  
the semantics), I didn't propose this one :)
