Hi, I have a concern about the note following Checkpoint 2.1 (Taken from the 20 December working draft): 2.1 Ensure that the user has access to all content, including alternative equivalents for content. [Priority 1] Note. Although it is not a requirement that alternative equivalents be available at the same time as primary content, some users may benefit from simultaneous access. For instance, users with low vision may want to view images (even imperfectly) but require a text equivalent for the image; the text may be rendered with a large font or as speech. I have been assuming that this checkpoint is the umbrella requiring UAs to provide access to multimedia alternative equivalents and that the later checkpoint 2.6 that requires synchronizing captions or auditory description is a special case of this. Since the note on 2.1 explicitly says that it is not a requirement to render at the same time, but 2.6 says that some tracks must be rendered synchronously, perhaps the note for 2.1 should say it is not a requirement for all alternative equivalents to be available at the same time as primary content, but see Checkpoint 2.6 for cases where that is required. -Madeleine
