Hi there, So as normal I'm thrashing this about - and I wanted comments on wording - I expect the wording here to change but here goes: 4.7.x Location in Hierarchy: The user can view the path of nodes leading from the root of any content hierarchy in which the structure and semantics are implied by presentation, as opposed to an explicit logical structure with defined semantics (such as the HTML5 Canvas Element), or as a consequence of decentralized-extensibility (such as the HTML5 item / itemprop microdtata elements), and only if the user agent keeps an internal model of the hierarchy which it does not expose via the DOM or some other accessibility mechanism. (Level A). In addition 3.3.1 says, 3.3.1 Access Relationships: Provide access to explicitly-defined relationships based on the user's position in content (e.g., show form control's label, show label's form control, show a cell's table headers, etc.). (Level A) Which feels to me like it should be in 4.7.x. thoughts? Finally, Internal representations and especially semantics known only to certain user agents, as described in HTML5 - item / itemprop to encourge decentralized-extensibility, worry the heck out of me and I think we need to make sure we have this covered - as well as all structured internal representations, such as may be possible in canvas, which are likewise not exposed to the user.
