This allows e.g. specifying that a certain freight charge is valid only for a certain quantity.\nNote that if an offering is a bundle, i.e. it consists of more than one unit of a single type of good, or if the unit of measurement for the good is different from unit (Common Code C62), then gr:hasEligibleQuantity refers to units of this bundle.
