     58   Each package starts with a header, as defined above, which
     59   indicates the size and type of the package. When added to a
     60   pointer pointing to the start of the header, Length points at
     61   the next package. The package lists form a package list when
     62   concatenated together and terminated with an
     63   EFI_HII_PACKAGE_HEADER with a Type of EFI_HII_PACKAGE_END. The
     64   type EFI_HII_PACKAGE_TYPE_GUID is used for vendor-defined HII
     65   packages, whose contents are determined by the Guid. The range
     66   of package types starting with EFI_HII_PACKAGE_TYPE_SYSTEM_BEGIN
     67   through EFI_HII_PACKAGE_TYPE_SYSTEM_END are reserved for system
     68   firmware implementers.
