The test date and enrollment date will typically be recorded as  
property values of instances. Test date will be something like an  
instance of test associated with a patient record. Enrollment date  
would be some value off an instance of study. So this *isn't* the  
specified cases where the two properties are of the same individual,  
rather the extended case.

The use case we decided on in HCLS is that where a researcher who is  
about to do an investigation is evaluating patient records to see who  
might be a candidate for a study. In that case the enrollment date  
would be known and the case reduces to testdate < constant.

Based on this, I propose we close ISSUE-53. Should another example  
show up we can open a new issue.
