Clarify the scope #27
Comments
+1, I'd love to have a good set of working examples to reason about. |
pinging @nolanlawson @gonzalocordero @caridy for support here. |
Fixes #27 I also went ahead and renamed "popup" to "popover," since [that's the new name](https://developer.chrome.com/docs/web-platform/popover-api/).
Opened a PR: #28 |
The list helps, but I think we need more. For each attribute, it would be good to have pointers to some usage examples, preferably in production code (e.g. a demo page for a component or whatever). I think the critical issue @annevk is trying to understand is whether for each attribute there's a tendency to refer either in to shadow roots or out of them, with a view to understanding whether something like CSS parts could do the job for both the referring-into problem and the serialization problem (i.e. that you could set things up so references always go inwards, and use a CSS parts-like design which is inherently serializable). I think I'm trying to generally understand the contours of the interlocking refer-into-shadow-root and serialization problems. For example, my assumption is that except in the "semantic delegate" type case (where the fact that you're referring into a shadow root is really an implementation detail), references into a shadow root involve some degree of knowledge of what's inside (e.g. if you're referring to an active descendant within a shadow root, you know that the thing you're referring to has an appropriate role). (This is why I find the CSS parts-style solution somewhat appealing, because it kind of makes that explicit by providing a "public API"; however, it wouldn't necessarily solve the serialization problem.) |
As far as I can tell there's only 8 ARIA attributes that can point to elsewhere in the tree. It would be useful to call those out to make it clear exactly what problems are attempted at being solved.
