Summary of Issue: The 'captions' definition implies that captions may be non-visual
Comment (Including rationale for any proposed change):
The Glossary defines "captions" as "synchronized visual and/or text alternative for... audio information", implying that captions may be non-visual. A non-visual text alternative does not achieve the intent of Success Criteria 1.2.2 and 1.2.4, to enable people who are deaf or hard of hearing to watch synchronized media presentations.

https://www.w3.org/TR/2008/REC-WCAG20-20081211/#captionsdef

Proposed Change:
"Captions" should be defined as "synchronized visible text alternative for... audio information".

Please include a correction in Editorial Errata for WCAG 2.0, and edit for clarity in a next generation of accessibility standards.
