I think "$" is a unit of measuring currency, and "barrel" is a unit  
of measuring oil, which in this case is the product the currency  
references.  Though used together here, these are two distinct  
problems that deserve separate microformats, one for currency and  
another for products (i.e. hListing).  Measurement of currency can be  
useful without considering measurement of products of purchase.  We  
should start with describing the simplest form of useful data.
