I think Bruce's suggestion and Gregg's text is sufficient to address this topic for folks who may be coming at the WCAG fresh and working out what they are expected to do.  It is important context for knowing what we mean as it relates to those different IT environments.

Subject: captions and subtitles

In our meeting today it was pointed out that WCAG refers to Captions  while some countries use the work Subtitles for the same thing.

When this occurred with audio description and video description we added the following note to WCAG2ICT

"Note: WCAG 2.0 definition of Audio Description says that Audio Description is "Also called 'video description' and 'descriptive narration.'".

We were going to use a similar statement here but it is complicate by the fact that "subtitles" is also used to refer to subtext that only contains the words and does not contain speaker identification or important non-speech sounds.

So the following is proposed as a note instead - that would be included on the caption provisions in WCAG2ICT:

"Note: The WCAG 2.0 definition of Captions says " In some countries, captions are called subtitles".  To meet this SC however they would have to be the type of subtitles that provide "synchronized visual and/or text alternative<http://www.w3.org/TR/2008/REC-WCAG20-20081211/#text-altdef> for both speech and non-speech audio information needed to understand the media content"
