If you're worried about CSS selectors 'bleeding through' how do functional selectors not have precisely the same concerns? I'm not saying it doesn't exist, I'm saying that I am having trouble envisioning it and would like some more information. It does seem to me that both sorts of isolation naturally 'fall out' of simply having a connector of trees that isn't using parent/child pointers and that most things would "just work" and be easy to explain (as a thing on its own and to use to build up higher features) which is an aspect I am having trouble seeing in nearly all other proposals. Once again, I'm not saying it's not there, I'm just asking for someone to explain/show me. Sure, here are some use cases I can think off the top of my head: Styling a navigation bar which is implemented as a list of hyperlinks Styling an article in a blog Styling the comment section in a blog article Styling a code snippet in a blog article None of these scenarios require authors to write scripts. - R.
