Add computed role section and mappings #167
Conversation

hey @cookiecrook and @scottaohara, I'd really like your opinion on this! Check out the githack to see how the tables look: https://raw.githack.com/w3c/core-aam/computed-roles/index.html#mapping_role And @cookiecrook, I'd really like to hear your take or expectations for the roles with are context dependent, and the other roles which are affected by the existence of attributes and accessible names. Have you gotten to thinking about those yet? |

so yes, I’ve been thinking about how to ensure we can test it all, but I have not been thinking deeply of how to specify it. Yours looks like a good start. It should probably also include a reference that contextual requirements may apply. For example, a cell in a valid row context should return a computedrole of cell, but an orphaned cell should not. |

We should discuss further how much we need to spec granularly vs leave to WPT edge case tests. For example, it would be tedious to spec all the built-in heuristics of what constitutes a valid data and I expect there will be some discussion of the purposeful implementation differences related to layout list-itis and an expectation of computedrole: thread: https://twitter.com/cookiecrook/status/1337226933822603270 |
I think this would be good to define, and HTML has a suggestion for the heuristic: https://html.spec.whatwg.org/multipage/tables.html#the-table-element
Getting interop on this also seems good imo. |

@cookiecrook this section is non normative so I think I will land it soon, maybe we can just leave this as "unspecified" for now.
Have you done any testing or thought about what the browser should expose as the computed role in this other scenario? I saw that you didn't add tests for it yet.

I recall writing some tests for orphaned elements, like <div role="listitem"> but I agree that we do not fully specify or test this yet.
For example, in the scenario:
<div role="listitemcheckbox checkbox"></div>It's not listitemcheckbox b/c of the missing context, but do we use the fallback concrete role, checkbox, or the native host language role, generic?
In any case, I agree its okay to leave unspecified in this PR.

Closes #166
The githack is easier to review, because the mapping tables code works (unlike in the PR preview, below): https://raw.githack.com/w3c/core-aam/computed-roles/index.html#mapping_role
