+/** @file
+  This file declares the hardware-device class GUIDs that may be used by the 
+  PEIM that produces the Virtual Block I/O PPI.
+
+  These GUIDs are hardware-device class GUIDs that would be imported only by the
+  Virtual Block I/O PEIM.  This virtual PEIM imports only the actual Block I/O 
+  PPIs from the device-class ones listed here and published a single instance of
+  the Block I/O PPI for consumption by the File System PEIM.  In the parlance of
+  the Framework DXE software stack, this Virtual Block I/O PEIM is actually 
+  embodying the functionality of the partition driver.  Thsi Virtual Block I/O
+  PEIM has to multiple the multiple possible instances of Block I/O and also know
+  how to parse at least El Torito for CD-ROM and perhaps Master Boot Record(MBR)
+  and GUID Partition Table(GPT) in the future.
