+/** @file
+  Capsule Architectural Protocol as defined in PI1.0a Specification VOLUME 2 DXE
+
+  The DXE Driver that produces this protocol must be a runtime driver. 
+  The driver is responsible for initializing the CapsuleUpdate() and 
+  QueryCapsuleCapabilities() fields of the UEFI Runtime Services Table. 
+  After the two fields of the UEFI Runtime Services Table have been initialized, 
+  the driver must install the EFI_CAPSULE_ARCH_PROTOCOL_GUID on a new handle 
+  with a NULL interface pointer. The installation of this protocol informs 
+  the DXE Foundation that the Capsule related services are now available and 
+  that the DXE Foundation must update the 32-bit CRC of the UEFI Runtime Services Table.
