Then IMHO all templates which preapply selection_mux should also
declare a trap __selection_mux_kind that returns their selection mux
"class".

Actually, this is a great example of why instanceof is a bad
thing... if you created a new kind of radiobutton that should be
"grouped" with other radio buttons, but doesn't use the same template,
there would be no way to "fake it out" if XWT gave you an instanceof
primitive.
