Why <datagrid>? I think <select> is just enough in this case as
<optgroup> can contain other <optgroup>s now.

Problem with <select>/<option> is that they do not allow
markup inside - only plain text. This limits its use significantly.

About Tabbed content:

Tabs control is a binding of set of radio buttons (or labels that behave as 
radio buttons)
with the set of panels. Value of radio group is bound to the visibility of 
panel. This schema works perfectly if stripe of labels and panels are 
independent DOM
elements. But when labels and panels are combined into single element like 
it is impossible to define reasonable layout using CSS in its current state.

This, btw, reminds me the question I wanted to ask while ago:

All elements introduced by html5 should appear in
"master" style sheet similar to this: http://www.w3.org/TR/CSS1#appendix-a
otherwise if they will use some non CSS definable layout we
 will end up with another <table>s situation.
There are few elements emerged already that are impossible to define in CSS 
<footer>  and <header> are examples that I can recall immediately.

So is the question: does this imply that HTML5 shall have synchronous CSS5 
or not?
