I agree, RDFa and Microdata are clearly extension mechanisms. That said,
I believe Julian and Larry disagree because they appear to believe an
extension mechanism must allow for the addition of novel elements and
attributes, e.g. <foo bar="">baz</foo>. Julian, Larry, please correct me
if I've misunderstood you.

I think this is why any discussion of distributed extensibility ends up
with people talking past each other: some people believe such
extensibility requires the ability to make custom things go right after
the < sign, and some people don't. (FWIW, I don't.)
