+Provides the data format and Name and GUID definition for the EFI Variable ACPI_VARIABLE_SET and the Framework version's correponding \r
+EFI Variable.\r
+This variable is the persistent data that will be saved to NV EFI Variable. It is the central repository\r
+for configuration data saved by the CPU Driver, Platform SMM Handler. It is read by \r
+Platform PEIM and PEIM on S3 boot path to restore the system configuration.\r
