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

As different user groups rely on either or both the title element and page title (typically h1) to identify the current page I'd like to see the SC requiring the page title and title element being somewhat in unison - that is providing the same information per rendered page.

> [Jason] I’m wondering whether 2.4.2 (properly applied) already covers it. Consider the single page application. If it satisfies 2.4.2 after it first loads, but most of the content is changed by a script during the user’s interaction so that the title no longer describes the “topic or purpose”, what do we say about conformance? This is a much larger issue than 2.4.2, of course.

At some points during the interaction there will be images on the page that lack text alternatives, yet we don’t want to say that the page fails to conform as a result. I suspect there’s a WCAG definition somewhere that addresses this issue, but I’ll have to re-read the document and look carefully for it.
