Rule 4: Codec_Specific_Configuration parameters shall be present at Level 2 and may be present at Level 3. If an identical Codec_Specific_Configuration parameter value is present at Level 2 and at Level 3, the Codec_Specific_Configuration parameter value at Level 3 shall be treated as the only instance of that Codec_Specific_Configuration parameter value present. Where a Codec_Specific_Configuration parameter value includes length-type-value (LTV) structures, an LTV structure shall be considered an identical parameter to another LTV structure with the same Type field value, and the Value field of the LTV structure at Level 3 shall be treated as the only instance of that Value field that is present. -- This is an automated message from the Apache Git Service.
