Still working on that.

I think Micah Dubinko explained it best, in his position paper to the
W3C's recent Web Apps workshop:

IE6 is only a concern because compatibility with IE6 is a concern of Web
authors. The main motivation of WF2 (and all of WHATWG) is authors.

If you say so.

XHTML 1.0 appendix C claims to describe such a migration path. But that's
a question for the W3C, WHATWG is merely making extensions apply to both
so that if someone wants to use one instead of the other, they can. Since
as far as UAs go they are mostly equivalent, it's no big deal.

Fair enough. In that case innerHTML/outerHTML/clientWidth/clientHeight
and so forth. There are plenty of examples of extensions to the DOM that
polute the DOM namespace.

* Publish WF2 snapshot this weekend.
* Iterate WF2 until we agree it is as good as we're going to get it
without real-world experience.
* Create WF2 test suite.
* Create WF2 experimental implementations, to obtain implementation
* Update the spec based on implementation feedback.
* Submit WF2 to standards organisation as basis for HTML extensions.
* Publish WA1 requirements.
* Make new roadmap.

We're getting quite enough feedback as it is! ;-)
