But how are things to be aggregated? In some cases (like hReview's  
"rating"), the aggregate might be the numerical mean of the  
individuals. For other fields, the median, the mode or the range  
might be more suitable. For yet others, perhaps it would be desirable  
to see the sum of the individuals.

For example, say you're creating an aggregate hCalendar event. Using  
an average dtstart and dtend is probably not very useful, but taking  
the earliest dtstart and latest dtend might be.
