5 ISO/IEC :2006/Amd.1:2007(E) 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. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Amendment 1 to ISO/IEC :2006 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.

Conformance testing of the BiM Encoder is not provided. 9.2 Bitstream in Access Unit Form The binary bitstream in access unit form (together with its associated binary DecoderInit) is fed to the reference systems decoders. The decoded information is used to reconstruct a document after each access unit. Each resulting document is tested for validity against the schema declared in the associated DecoderInit. The following conditions must be fulfilled as a necessary condition for each binary bitstream in access unit form: 1) The syntax of each binary access unit as well as the syntax of the binary DecoderInit must be correct wrt. the BiM syntax as defined in Clauses 6, 7 and 9 of ISO/IEC ) Decoding the document fragment conveyed in the InitialDocument together with the document fragment conveyed in the first access unit must result in a document that is valid against the schema declared in the DecoderInit. 3) After each access unit the decoded document must be valid against the schema declared in the DecoderInit. 4) In any FUU, when the FU command is add then the FU context must not point to an instantiated node in the current document tree. 5) In any FUU, when the FU command is update or delete then the FU context must point to an instantiated node in the current document tree.
