That could attempt to get the first element of a None type, if the 'product'
qualifier doesn't exist.
Actually, I wrote it that way so it could be extended.  First it would try
'product' and if that didn't exist replace it with something like a
'db_xref' or a 'note' entry.  I was hoping to get some input on what people
think would be 'order of importance' of things to try.
