[jnurthen]

per plans for role parity need a role for equivalent to <iframe> in HTML

This is too late for 1.2 - moving to 1.3

Sorry for dropping the ball on this! I accidentally unassigned myself when doing some batch unassigning.

@scottaohara recently commented on embed

In drafting up a potential definition for this role, and re-reviewing what object and embed are meant to represent, I'm wondering if this might be similar to generic in that this role is more meant for implementors rather than authors.

Being that these elements largely embed content that could be considered graphics or other media (videos/audio), nested browsing contexts (application or document roles) or plugins like flash, i'm unsure why we'd want authors to use this role when it'd be more straight forward to use other roles that better represent the embedded content.

This resonated with my thoughts on iframe. It also does not feel like a role for authors.

w3c/html-aria#368 seems relevant; James Teh's comments show how particular iframe implementations are. It seems questionable to me that ARIA could reach parity here.

@pkra, suggest we punt this to 1.4 since the embed/object one is slated for 1.4 as well

This is already in the 1.4 milestone. (All remaining role parity issues now are, so I renamed that project board.)

I definitely think iframes should have a generic role. If authors need something else they can add a non-generic role like "section" or "complimentary", in which case a name would be required. Generic iframes should not require names or lang attributes.

iframes that do require names (i.e. those marked-up with a non-generic semantic role) might usefully inherit their accessible name (and language) from the title (and lang attribute) of the HTML content inside (if one exists) in a similar way to how the first heading inside a semantic element is taken to be the accessible name of that element.
