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