ISSUE-53
http://www.w3.org/2007/OWL/tracker/issues/53

is also a relevant usecase for n-ary datatypes.
[[
I need the ability to say something like:
Patient that (testdate > enrollmentdate + 60)

Was trying to represent the following inclusion criteria in a clinical 
trial:

The patient must have negative gadolinium based MRI of the contralateral 
breast, no more than 6 months prior to study entry.
]]

I am curious as to whether this can be met without defining a class of 
patients with this property. e.g. is preprocessing adequate, or maybe a 
posthoc SPARQL query of some results - rather than a declarative 
definition of a class of patients based on a numeric computation.
