I left out the ternary (?:) operator in (3a):

(3a) underspecify document.all as a host object property that may be  
reliably tested only by if, &&, ||, == null, == undefined, and ! and  
the != counterparts. Anything else is unspecified behavior.

I also left out loops and switch; we've never seen these statements  
used to detect document.all so in the interest of underspecifying, I  
left 'em out here.
