Yeah, we should figure something out here. From one perspective you've
already namespaced your element by using a dash. However, given the
existence of an ever growing set of global attributes you probably do
not want to clash with those.

Maybe we should allow any attribute as long as it contains a dash (and
does not match a set of existing names)? Still seems somewhat
