Description

Reference Targets allow forwarding IDREFs to members of the ShadowDOM which will make it signficantly easier to create web components which rely on ARIA (which itself heavily relies on IDREFs).

The Web Components Community Group considers this a pivotol feature.

I think some relationships should be implicit as we don't want to regress on how label works today: WICG/aom#209.

Overall though I like the direction this is going in.

Now that w3c TAG has blessed phase 1 of this API and Chromium is moving into experimentations with it, when do you think can we expect to hear positioning from Webkit on this API?

[annevk]

People are generally excited about this solving a set of a11y problems with shadow roots, but generally we only take a position once there's more formal specification text to review. @LeaVerou's concern around non-ARIA attributes is also quite interesting. Was that addressed anywhere?
