However, check me here: the GSP makes "own" global properties on demand, 
when names of DOM elements that come from name= and id= attributes (or 
just id=? I forget) are used as identifier expressions.

So at least the GSP is not adding a new tier of proto-properties (again, 
I hope! Please correct me if I'm mistaken).
