In subclause 5.5.3 replace the third and fourth paragraphs with: Backward compa
6、tibility is provided by the unique reference of the used schema in the DecoderInit using its Schema URI as its namespace identifier. Forward compatibility is ensured by a specific syntax defined in Clauses 6 and 7. Its main principle is to use the namespace of the schema, i.e., the Schema URI, as a
7、unique version identifier. The binary format allows one to keep parts of a document related to different schema in separate chunks of the binary document stream, so that parts related to unknown schema may be skipped by the decoder. In order for this approach to work, an updated schema should not be
8、 defined using the ISO/IEC 23001-1 “redefine” construct but should be defined in a new namespace. The Decoder Initialisation identifies schema versions with which compatibility is preserved by listing their Schema URIs. A decoder that knows at least one of the Schema URIs will be able to decode at l

In subclause 5.6, replace the seventh item of the third paragraph with: - The DL shall provide a means to deliver the DecoderInit information (see subclause 6.2) to the terminal before any access unit decoding occurs.
