Section 3.3 says:
One of the OTI values for 'mp4a' is 40 (identifying MPEG-4 audio). For this value, the third element identifies the audio ObjectTypeIndication (OTI) as defined in [MP4A] (including amendments), expressed as a decimal number.
It should say:
One of the OTI values for 'mp4a' is 40 (identifying MPEG-4 audio). For this value, the third element identifies the AudioObjectType (AOT) as defined in [MP4A] (including amendments), expressed as a decimal number.
Notes:
[MP4A] "Information technology--Coding of audio-visual objects -- 3: Audio", ISO/IEC 14496-3:2009. Only speaks of ObjectTypeIndications in the context of systems OTIs in the previous paragraph and never mentions "audio ObjectTypeIndication". In the example that follows the third element is an "AudioObjectType".
