Think about this:

table#spreadsheet > td:not(:first-child)
   behavior: single-line-edit;

<table id="spreadsheet">...

It will declare all cells in the table (except in first column) to be 

   input[type="radio"] { behavior: pop-up-menu; }

will replace intrinsic behavior:radio by the new one for applied 
elements.  May or may not have any sense.

But (css) : 
   menu { behavior: menu-bar; }
   menu menu { behavior: pop-up-menu; }
   menu menu li.option { behavior: radio; }

does have sense. Isn't it?
