allow doc-* link roles on area with href

[rdeltour]

consider allowing the following roles on area with href:

• doc-backlink
• doc-biblioref
• doc-glossref
• doc-noteref

@rdeltour it looks like this was already merged into the spec, but in reviewing it again today I have a question about doc-noteref.

Should that role be allowed on a <a href> or is it meant to not act as a link? The example in the ARIA DPub spec uses it on an <a> without an href, which either seems like an oversight with the example in the DPub spec, or I need to allow it on <a> and not <a href> here.

Thanks

As far as I'm were it's clearly meant to be used as links (and it subclasses the link role), so yes I think it's an oversight in DPUB ARIA’s example 30.
Typically the noteref would be used both as a link to the actual note, plus also as an anchor for a backlink, but I don't think I've ever seen it used as an anchor only.

Pinging @mattgarrish (who's the DPUB ARIA editor and master of all EPUB/DPUB specs 😊) for confirmation.

Yes, that's definitely a mistake in the example. An inactive note reference is somewhat useless; it's not something I'd expect to see done in the wild. I've opened an issue in the dpub aria tracker.

Then looks like this issue is good to close, because all those roles are in the Spec now.
