Wasn't this discussed during all the focus discussions during the W3C  
Technical Planery? If not, I wonder why :-)

Is that a property, attribute, event? How exactly would that work?

Given that more groups ought to be involved (the CSS WG has focus  
navigation in a CR spec for some time now) I'm not sure the CDF WG can  
decide that. However, I'm not speaking for the group.
