Should "Link has non-empty name" apply to inheriting links? [c487ae]

[WilcoFiers]

I noticed this rule applies to semantic links. Seems to me this should also apply to inheriting semantic links.

On the other hand though, should we expect anyone testing HTML to support DPUB? Should that be in a separate rule?

Maybe we can have a failing example with <span role="doc-biblioref link"> so that:

• tools that don't support DPUB fail that as being a semantic link without name;
• tools that support DPUB and correctly check for non-empty name of inheriting semantic links fail that;
• tools that support DPUB but only check for non-empty name of semantic links (non inheriting ones) incorrectly pass that.

That way, tools that don't fail the example are tools that do not correctly implement the rule within their ARIA capacities; and we don't "punish" tools that chose to ignore DPUB.

[WilcoFiers]

The role attribute has valid value rule already has an example that requires support for DPUB. That suggests we shouldn't limit our rules to wai-aria proper here either. Discussed on the call, group agrees adding these roles to the rule would be appropriate.
