Sure we can conceptualize it like that, but if no one is publishing  
it like that, how will we microformat it?  I've never seen "$/barrel"  
on the web, so this looks like an edge case to me.  I have seen "$__  
per barrel", and that splits the unit of currency and the unit of  
measuring the product, just like "$__ per share" (implied 1 unit) or  
"$__ for 2 widgets".  It looks to me like splitting up the unit of  
currency and the unit of measuring the referenced product would cover  
80% of real world examples, so I'm not seeing the value in exploring  
the edge case where the two are combined.  If it's clear that my  
product is a barrel of oil (which hListing can make clear) and my  
currency is US dollars (which a simpler currency microformat can make  
clear), why can't we leave it to a computer to figure out how to most  
usefully combine those two pieces of information?
