Sort of.  We have had (in the past as well, imo, in the future) a requirement for decentralized extensibility - that is, that document/content authors can extend the set of elements with their own semantic or behavioral elements.  I continue to think there is a requirement for that.  (One might well ask why we didn't implement full XML in that case; I'll politely not answer from a historical context, but will point out that the draconian error handling and poor fallback story make delivering content in XML in the browser a poor solution in the ecosystem today.)

I'll take a stab at it.  I think it's a very thorny issue, and I do not expect to have a perfect suggestion.

Of course.

I'd say I think it would be a distinct mistake to not have decentralized extensibility.  I think namespaces are a convenient, somewhat familiar way of thinking about that, but not perhaps the only way.
