So, that would squarely contradict Ian's point that we can "already ado
this with existing HTML extensibility."

But let's dig in for a second. Incompatible with what? What principle of
HTML or existing feature of HTML would be broken by adding metadata into
content? (Not to mention that Julian is right, the distinction between
metadata and data is often irrelevant.)

Also, does that mean microformats go against the principle of HTML?
After all, they include calendar event markup in the HTML body.
