I want to describe three different packaging configurations of the same product that has the same marketing act. I have a 100-tablet bottle, a 60-tablet bottle, and a 30-tablet bottle. My initial thought was to have 3 PackagedProductDefinitions that referred to the same ManufacturedItem. The ManufacturedItem describes the tablet and the PackagedProductDefinitions describe the bottle. But I have a problem in putting the 100/60/30. The PackagedProductDefinition.packageItem.quantity field says "The quantity of this package in the medicinal product, at the current level of packaging. The outermost is always 1". So it seems like this should be 1 for all three of my PackagedProductDefinitions. The ManufacturedItemDefinition.quantity descriptions says "The quantity or "count number" of the manufactured item", so that seems the spot to put the 100/60/30, but then I have to make three different ManufacturedItemDefinitions whose only difference is the quantity.

I think that we need to move the quantity field from the ManufacturedItemDefinition resource to the PackagedProductDefinition resource. Something like:\\./manufacturedItem
../quantity - the quantity or count of this manufactureditem in the packageItem
../itemDefinition - the details of the manufacturedItem
