Can anyone on the list help with this discussion? thanks in advance. No..actually this still doesn't clarify it for me..I read that info online, too...which at least helped me to guess that 1.4 referred to syncying. But what I still don't understand..text equivalents INCLUDE auditory descriptions...SO how does including auditory descriptions help when the priority states that some user agents can't read them automatically? And what are they referring to when they talk about text equivalents if not auditory descriptions? And if user agents don't automatically read them, how does adding additional text equivalents solve anything? And Why would you need an additional priority to tell you that these auditory descriptions need to be in sync? In my mind, 1.3 is still trying to say something different..and I don't really know what... snip > > http://www.w3.org/TR/1999/WAI-WEBCONTENT-19990505/#gl-provide-equivalents > > 1.3 Until user agents can automatically read aloud the text equivalent of a > visual track, provide an auditory description of the important information > of the visual track of a multimedia presentation.
