A video includes text content that is positioned in the space used by closed captions, so the captions appear overlaid on the text. I'm wondering whether this is an SC 1.2.2 failure and it seems to rest on which part of the SC is normative.
WCAG SC 1.2.2 says "Captions<https://www.w3.org/WAI/WCAG22/Understanding/captions-prerecorded.html#dfn-captions> are provided for all prerecorded audio content in synchronized media...". But in the SC text, the word "Captions" is a hyperlink to a definition of that term which includes a note "Note 4. Captions should not obscure or obstruct relevant information in the video". I assume that the definition of "Captions" is normative. But is the note within the definition also normative? Would it be true to say that if captions do obscure relevant information in the video then they don't meet the definition of captions and therefore can't be used to satisfy SC 1.2.2? And does the word "should" within the note make any difference to this interpretation?
