Re: EARL Testcase

That would work (so long as you promise to put it in quotes so it is valid

Alternatively (or as well) we could ask the WCAG group to provide some
identifiers which we could then use in techniques notes too. I recall trying
to do this once, but I think it might have been for Authoring Tools - there
should be something in there that makes sense as an identifier. But I can't
guarantee it... (And checking, it turns out to be a figment of my imagination

Until I could use OWL to explain the realtionship in a machine-readable way I
haven't really bothered including conformance level claims in the work I have
done (since they were not terribly relevant to the aspects that were
important to what I was doing).
