super set relation

A super set relation defines one collection as the super set (base collection) of another collection. Super set relations are the inverse definition of subset relations, i.e. defining a super set B for a set A automatically creates a subset A for B. Typically, super set relations are defined for extents. For local collections, super set relations are defined as base collections.

For controlled extents, super set relations can be defined explicitly, which automatically implies the definition of a subset for the defined super set.
