Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of document should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or

whether or not correctly received, shall not be modified; they shall either:
— be encapsulated altogether in one partial segment and stored in a PartialDataBox, or
— be encapsulated altogether in an OriginalFileTypeBox immediately following the new FileTypeBox
of the mixed partial file.
This ensures that a single FileTypeBox is present at the container level.

5.1.9 and 5.1.10
