CIM_BasedOn is an association describing how storage extents can be assembled from lower level extents. For example, protected space extents are parts of physical extents, while volume sets are assembled from one or more physical or protected space extents. As another example, cache memory can be defined independently and realized in a physical element or can be 'based on' volatile or non-volatile storage extents.

'EndingAddress indicates where in lower level storage, the higher level extent ends. This property is useful when mapping non-contiguous extents into a higher level grouping.'
