RE: Proposed SC: Unique Titles - or - Unique & Updated Titles

Ø  [Jason] The granularity of conformance is the “Web page”, so it isn’t clear what “screens” or “views” are or how they relate to Web pages – the units of conformance for WCAG. After reading the above, it isn’t at all clear to me what this proposal means.

The challenge we have is that a viewport within a single page may need a different title than another viewport within the same page.  For example, some pages use snap to scrolling where different whole screens are loaded when you scroll but it’s all the same document.  In mobile apps we have screens and not pages – right now with WCAG to non-web ICT only the app needs a title and there is no requirement for screen titles for each screen of a native mobile app.

​​​​​I would like to start the conversation with WCAG with this suggested wording:

Web pages and screens (views?) have titles that are unique (to the site or application) when rendered.


[Jason] The granularity of conformance is the “Web page”, so it isn’t clear what “screens” or “views” are or how they relate to Web pages – the units of conformance for WCAG. After reading the above, it isn’t at all clear to me what this proposal means.
What we could say (based on existing definitions) is, for example, “The title of every page within a set of Web pages is unique with respect to that set of Web pages”. I’m not satisfied with this wording, but it’s closer to what I think we could easily propose. Now, what isn’t clear to me is how Katie’s proposal is intended to go beyond this, as I understand it is meant to do.
The underlying notion in my proposal here is that we take the same set of Web pages which is used for determining conformance, and require that they all have unique titles (that is, unique compared with other pages in the set). If all that is said to conform to WCAG is a single page, not a set of pages, then obviously the proposed SC wouldn’t apply. The restriction to the set of Web pages also entails that titles need not be unique throughout the Web, or throughout the universe of digital documents, etc., which is far too burdensome a requirement and impracticable to evaluate.
I would also be interested to know what accessibility benefits this proposal has; I assume they’re largely cognitive (by which I don’t just mean that they help people with cognitive disabilities). Still, a good case should be made that they affect users with disabilities differently from users in general.
