New rule: F63 - link-context

F63 - link-context

This test verifies whether the purpose of the link can be determined by its context and if the purpose is not ambiguous.

Tags: wcag2a, wcag244, cat.semantics, experimental

Selector

Select each node with an anchor a[href] or role=link .

Checks

semantics/link-context ( any )

semantics/link-context-p

• Find the context by looking for the closest parent/ancestor p element
• Return true it the context element does not contain another link with the same link text

semantics/link-context-li

• Find the context by looking for the closest parent/ancestor li element
• Return true it the context element does not contain another link with the same link text

semantics/link-context-table-cell

• Find the context by looking for the closest parent/ancestor td or th element
• Return true it the context element does not contain another link with the same link text

semantics/link-context-header

• Find the context by looking for the closest preceding header
• Return true it the context element does not contain another link with the same link text

semantics/link-context-link-role

• Check that links with the same text don’t have the same context elements. If true, pass; else fail.

semantics/link-context-aria

• Check if the link context can be programmatically determined by using a WAI-ARIA property such as aria-label, aria-labelledby or aria-describedby on the link.
• Return true if found, else fail.

[WilcoFiers]

• experimental is just an additional tag.
• The selector should be: a[href] or [role=link]
• As for breaking it up in checks, I meant for it to look like this:

## semantics/link-context-p ( any )

- Find the context by looking for the closest parent/ancestor `p` element
- Return true it the context element does not contain another link with the same link text

## semantics/link-context-li ( any )

- Find the context by looking for the closest parent/ancestor `li` element
- Return true it the context element does not contain another link with the same link text

## semantics/link-context-table-cell ( any )

- Find the context by looking for the closest parent/ancestor `td` or `th` element
- Return true it the context element does not contain another link with the same link text

... etc
