810 database events have this prototype. The actual event is encoded
811 in NotifyType. The following table describes how PackageType,
812 PackageGuid, Handle, and Package are used for each of the
815 @param PackageType Package type of the notification.
817 @param PackageGuid If PackageType is
818 EFI_HII_PACKAGE_TYPE_GUID, then this is
819 the pointer to the GUID from the Guid
820 field of EFI_HII_PACKAGE_GUID_HEADER.
821 Otherwise, it must be NULL.
823 @param Package Points to the package referred to by the
824 notification Handle The handle of the package
825 list which contains the specified package.
827 @param Handle The HII handle.
829 @param NotifyType The type of change concerning the
831 EFI_HII_DATABASE_NOTIFY_TYPE.
