Consider accessible description in the rules that use link context (5effbb, fd3a94)

[carlosapaduarte]

Update rules that use link context to consider the title attribute. Although the original resolution in #1766 requested the changes to be made on the "Programmatically Determined Link Context" definition, given that this specifies a set of elements, it does not seem doable. As an alternative, I've added the accessible description to the expectation of "Link in context is descriptive" and to the applicability of "Links with identical accessible names and context serve equivalent purpose"

Closes issue(s):

• closes Should rules about link's name (b20e66, 5effbb, aizyf1, fd3a94) consider the title attribute? #1766

I feel it would be cleaner to remove aria-describedby from "Programmatically determined link context". Since the rules now explicitly mention the accessible description, that already includes aria-describedby references (and actually a few more things such as children of aria-describedby references, if I get the accessible name computation correctly).

So, the PDLC would be some set of elements defined by some DOM tree relationship, and rules about context would look at PDLC + accessible description.
(it would also means that aria-describedby="foo bar" and aria-describedby="bar foo" would be considered as different accessible descriptions while they are currently the same PDLC, which sounds bad)

Minor suggestions made.

Would be helpful to say "same non-empty accessible name, empty accessible description..."?

I added it in a couple other spots.

I like Kathy's suggestions on these, would like to see them made.

Good suggestion. I'm updating the definition accordingly.

Should we have our own def of it (like for accessible name?), I'm notably thinking we should link it to the "accessible name and description computation" document.

[carlosapaduarte]

Added a definition of accessible description

Editorial changes for consistency

I'm not sure this is obviously correct. The SC talks about link text and programmatically determined context. Its probably worth putting in the assumption that we're using "link text" from WCAG to mean accessible name and description. Links that fail label in name could have visible text that isn't considered "link text" in this rule. I think that should be in the assumption.

Assumption added
