In the case of [[ProductModel]], this is a pointer (from a ProductModel) to a base product from which this product is a variant.

In the case of a [[ProductGroup]], the group description also serves as a template, representing a set of Products that vary on explicitly defined, specific dimensions only (so it defines both a set of variants, as well as which values distinguish amongst those variants).
