+ Description (
+ "BasedOn is an association describing how StorageExtents can be "
+ "assembled from lower level Extents. For example, "
+ "ProtectedSpaceExtents are parts of PhysicalExtents, while "
+ "VolumeSets are assembled from one or more Physical or "
+ "ProtectedSpaceExtents. As another example, CacheMemory can be "
+ "defined independently and realized in a PhysicalElement or can "
+ "be \'based on\' Volatile or NonVolatileStorageExtents." )]

+ "EndingAddress indicates where in lower level storage, "

+ uint64 EndingAddress;
+
+ [Description (
+ "If there is an order to the BasedOn associations that "
+ "describe how a higher level StorageExtent is assembled, "
+ "the OrderIndex property indicates this. When an order "
+ "exists, the instances of BasedOn with the same Dependent "
+ "value (i.e., the same higher level Extent) should place "
+ "unique values in the OrderIndex property. The lowest "
+ "value implies the first member of the collection of "
+ "lower level Extents, and increasing values imply "
+ "successive members of the collection. If there is no "
+ "ordered relationship, a value of zero should be "
+ "specified. An example of the use of this property is to "
+ "define a RAID-0 striped array of 3 disks. The resultant "
+ "RAID array is a StorageExtent that is dependent on "
+ "(BasedOn) the StorageExtents that describe each of the 3 "
+ "disks. The OrderIndex of each BasedOn association from "
+ "the disk Extents to the RAID array could be specified as "
+ "1, 2 and 3 to indicate the order in which the disk "
+ "Extents are used to access the RAID data." )]
