In discussion it emerged (i.e., Mary Holstege noticed!) that we can't simply get
rid of op:yearMonthDuration-equal and op:dayTimeDuration-equal because the
definition of op:duration-equal invokes these functions implicitly. On the other
hand, the definition of equality on the two subtypes is not saying anything very
profound. So we probably need a revised definition of op:duration-equal, in
which case the other two functions can be dropped. I was actioned to write a
concrete proposal.
