               current time. 
               It would be equally valid to have a longer range of 
               time over which this statement was represented as 
               being true. As a maximum, you would never indicate 
               an effectiveTime/high that was greater than the 
               current point in time. This idea assumes that the 
               value element could come from the Problem value set, 
               or when negationInd was true, is could also come from 
               the ProblemType value set (and code would be ASSERTION). -->
