Via Twitter (where else) news reached me about the CSS Namespaces Module. It is the first specification I edit (together with Elika) that reached the near-magical W3C Recommendation status. The irony here is that I dislike namespaces, a lot. From all specifications I edit this is probably the least useful one. It contributes to namespace confusion and defines a legacy feature (
@namespace) mostly intended for usage by browser vendors directly. Authors can leave it.
