assuming that you talk about text captions here: one
version is enough
the following example from the SMIL REC shows how this works,
see
http://www.w3.org/TR/REC-smil/#test
====
In the following example, captions are shown only if the user wants captions on.
...
<seq>
<par>
<audio src="audio.rm"/>
<video src="video.rm"/>
<textstream src="stockticker.rtx"/>
<textstream src="closed-caps.rtx" system-captions="on"/>
</par>
</seq>
...
====
The second textstream object is only shown if the "system-captions"
test attribute evaluates to "true", which is the case when the
user has requested captioning
Lloyd proposed a similar test attribute to switch audio descriptions
on and off (see my previous message)
