+// other internal firmware data variables that are not defined here must be\r
+// saved with a unique VendorGuid other than EFI_GLOBAL_VARIABLE or\r
+// any other GUID defined by the UEFI Specification. Implementations must\r
+// only permit the creation of variables with a UEFI Specification-defined\r
+// VendorGuid when these variables are documented in the UEFI Specification.\r
