Indeed. While in practical terms many people will use tests and not  
completely understand the spec, I think it is valuable to name one thing  
that is meant to be a priori right in cases of conflict.

If there is a difference, and ergo a bug, it is true that both the spec  
and the test should be looked at to see the best way of making the world  
clearer and better, but allowing multiple normative definitions doesn't  
seem terribly helpful. Making one source be normative ensures that if we  
have a working process, we know where to look - and if we don't have a  
working process then multiple sources won't save us.

So I think the tests should be agreed by the WG one by one, but I don't  
think they should be normative.
