/**

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

  @param Length The size of the package in bytes.

  @param Type   The package type. See EFI_HII_PACKAGE_TYPE_x,
                below.

  @param Data   The package data, the format of which is
                determined by Type.
