Re: Audio description in WCAG 2.1 AA success criterion1.2.5

Note 2 to the audio description definition in WCAG states "In standard audio description, narration is added during existing pauses in dialogue. (See also extended audio description.)" which seems to scope the definition of audio description to existing pauses - hence why the understanding document is written toward that slant. While definitions are normative - notes are not. it does indicate that was the intention when the note was written - perhaps the note could be updated if the Accessibility Guidelines working group determines today that the technology reasons for that note in 2008 are no longer relevant.
