Export link type manifest

[marcoscaceres]

Over on w3c/webref#114, we are trying to figure out what the best way to export these "link type X" might be.

Problem is that they were available in BikeShed/Shepherd, but currently Webref doesn't have them (so I've got some broken links over in the manifest spec).

Open suggestions on how to best export this.

Happy to do the others once we settle on something.

FWIW, my preference would be:

<h5><dfn export data-lt="manifest">Link type "<code data-x="rel-manifest">manifest</code>"</dfn></h5>

So I can:

Continue to link to it like: [=link type "manifest"=]

I think we could use attr-value as per https://tabatkins.github.io/bikeshed/#dfn-types though since there's also the Link header this might call for a new type, such as linkrel or some such.

+1 for attr-value. Then you'd use for="link/rel".

[marcoscaceres]

Ok, cool. This now matches "preload", which is exported in the same way.

Let me know if you want me to export the other link types. I can send a separate PR for those if you'd like.

This looks good!

I do think we should export all link types. This is a bit more complex because some should be for="link/rel", some should be for="a/rel", some should be for="a/rel,link/rel,form/rel", etc. See https://html.spec.whatwg.org/#linkTypes

Let me know if you want to do that in this PR, or in a followup! I'd slightly prefer a single PR but I don't want to block you if you have other work depending on this getting merged.

[marcoscaceres]

If it's ok, I'd like to get this merged in first as it's currently affecting at least one spec.

I can follow up with the other exports as I think the ARIA in HTML spec also needs the exports you mentioned with the correct for= precision.
