I guess I was a bit over dramatic with "overhaul the language" :). It doesn't mean any changes to implementations, but it does change a lot of other aspects. It does change what is "valid HTML" (though the usefulness of that term is debatable), and it does change logistics in that now HTML is run through a registry in addition to a working group. And it also creates the problem you mentioned earlier of people rushing to register short prefixes, not to mention that we'll probably end up loosing good names to defunct projects and companies. >> > 2) Clear separation between extended attributes and custom attributes >> > added by the page author >> >> I'm not sure I understand the distinction.

Though arguably the data-foo-bar vs. data-bar distinction does that already. At least if people play nice. And if people don't play nice there is nothing preventing page authors using attributes named asp-backgroundcolor. >> > > What I prefer is a best effort solution.

The spec already recommends libraries on how they should use data attributes. Seems like it could go in as part of that. / Jonas
