Errata: Section 5.1 appears to offer conflicting requirements about closed functionality
Errata: Section 5.1 appears to offer conflicting requirements about closed functionality
5.1.2.1 Closed functionality
Where ICT has closed functionality, it shall meet the requirements set out in clauses 5.2 to 13, as applicable.
Specifically referring to 5.2 to 13, but not 5.1, where the note immediately following says:
NOTE 1: ICT may close some, but not all, of its functionalities. Only the closed functionalities have to conform to the requirements of clause 5.1.
So the first question is, Should 5.1.2.1 refer to "clauses 5.1 to 13" rather than "clauses 5.2 to 13"?
A second, related issue is that most of the clauses in section 5.1 do specify applying to "closed" functionality of a specific sort, but 5.1.3.6 does not. This one seems like a simple errata change to me.
5.1.3.6 Speech output for non-text content
Where ICT presents non-text content, the alternative for non-text content shall be presented to users via speech output unless the non-text content is pure decoration or is used only for visual formatting. The speech output for non-text content shall follow the guidance for "text alternative" described in WCAG 2.1 [5] Success Criterion 1.1.1.
