// Description: The Device Model extends the management concepts that
//              are related to LogicalDevices. This file describes
//              the modeling of storage hierarchies (extents,
//              volumes, partitions, etc.).
// 
//              The object classes below are listed in an order that
//              avoids forward references. Required objects, defined
//              by other working groups, are omitted.

// Change Log for v2.8 Final
// CR1202 - Remove Experimental Quaifiers
// 
// Change Log for v2.8 Final
// CR1027 - Clarify StorageVolume.NameFormat
// 
// Change Log for v2.8 Preliminary
// CR891 - Add NameFormat to StorageVolume
// 
// Change Log for v2.7 Final
// CR970 - Removal of the Experimental qualifier
//       - Remove several properties from StorageVolume and make them
//         Experimental in 2.8
// 
// Change Log for v2.7
// CR722 - Add ProtectedExtentBasedOn, CompositeExtent, and
//         CompositeExtentBasedOn
// CR882 - Deprecate Snapshot and SnapshotOfExtent. Therefore moved
