Needless to say Mark is upset about XHTML 2.0. Of course he shouldn't complain too loudly lest he get drafted as a technical expert by the committee.
What I find most puzzling is the lack of movement on XForms. As of now it looks like the only place it will make an appearance is in XHTML 2.0. I would really like to see an XHTML+SVG+MathML+XForms profile.
