Yeah, that belongs in CSS.

Whether an element (other than something purely presentational like a 
window) is draggable, whether an element is selectable, and whether an 
element is modifiable or editable are quite clearly not presentational 
aspects. They don't belong in the presentational layer, especially since 
that layer can be turned off.

IMHO.

As far as editing goes, contentEditable="" is the way we're going at the 
moment, I think. Focusable is probably going to be tabindex="". 
Selectable hasn't yet been discussed (I could be convinced that that is 
presentational, actually). Draggable is clearly not presentational; my 
current thinking is something like contentDraggable="" or something.
