+/** @file
+  Variable Architectural Protocol as defined in PI Specification VOLUME 2 DXE
+
+  This provides the services required to get and set environment variables. This 
+  protocol must be produced by a runtime DXE driver and may be consumed only by 
+  the DXE Foundation. The DXE driver that produces this protocol must be a runtime 
+  driver. This driver is responsible for initializing the GetVariable(), 
+  GetNextVariableName(), and SetVariable() fields of the UEFI Runtime Services Table.
+
+  After the three fields of the UEFI Runtime Services Table have been initialized, 
+  the driver must install the EFI_VARIABLE_ARCH_PROTOCOL_GUID on a new handle with 
+  a NULL interface pointer. The installation of this protocol informs the DXE Foundation 
+  that the read-only and the volatile environment variable related services are 
+  now available and that the DXE Foundation must update the 32-bit CRC of the UEFI 
+  Runtime Services Table. The full complement of environment variable services are 
+  not available until both this protocol and EFI_VARIABLE_WRITE_ARCH_PROTOCOL are 
+  installed. DXE drivers that require read-only access or read/write access to volatile 
+  environment variables must have this architectural protocol in their dependency 
+  expressions. DXE drivers that require write access to nonvolatile environment 
+  variables must have the EFI_VARIABLE_WRITE_ARCH_PROTOCOL in their dependency 
+  expressions.
