45 // are related to LogicalDevices. This file describes
46 // the modeling of storage hierarchies (extents,
47 // volumes, partitions, etc.).

49 // The object classes below are listed in an order that
50 // avoids forward references. Required objects, defined
51 // by other working groups, are omitted.
