Are we to understand that WHATWG is running without cooperation on
HTML5 development from the IE folk?

It's great that you have that.

However:

While in text/html the attribute markup xmlns="something" will at the
worst be taken by a user agent as a (relatively harmless) unknown
attribute, the use of xmlns:m="something" -- with a forbidden
character in an attribute name -- is a problem unless there is broad
acceptance that it should be allowed.

Furthermore:

In application/xhtml+xml there seems to be more than one understanding
among current user agents on the question (given the use of namespace
prefixing) of whether or not inside an "m:math" element unprefixed
subelements (at all depths) are mathml.
