We have a large number of tests that only link to drafts, this is fine.

There _is_ an issue however in that the canonical URLs for all the drafts has recently changed from http://dev.w3.org/csswg/... to https://drafts.csswg.org/...

I need to run through the test repository and update those links as they're currently broken.

If a test links to a spec that we are not yet building a test suite for, there's no issue. We do still validate if the link is to a known spec anchor or not.

At some point in the future we will start building a test suite for CSS 2.2 and then it will pick up all the tests that have links to the 2.2 draft.
