Yes, that didn't occur to me earlier: I didn't consider that some elements
in a document might not have to be rendered at all. It's obvious of course
but looking at the big picture I just didn't think about it. So now it makes
perfects sense that there are multiple structures doing different things
alongside the DOM tree. Thank you! This discussion was very informative!
