If this is an eligibility requirement, we wouldn't  
have"hasClinicalTrial, some EnrolledTrial". We only have that after  
they are determined eligible.

(I think you mean "enrollmentDate o hasClinicalTrial", BTW)

You might have a test like "can't have participated in another  
clinical trial  in the last 2 years"

In this case it would be equivalent, I think, as we are getting  
answers to the question "Which patients are eligible", which is a query.

Yes, this fits. It isn't part of our COI use case, but perhaps you  
can motivate it from other work of yours.

We can hold off for the moment, as there is a slight chance that the  
n-ary datatypes could include the ability to work with properties on  
different individuals.
