There is no way to make JavaScript so limited in scope as XSLT is.

But what I want only is XSLT on live DOM nodes, when editing. Simple templating good engine, and to stay. Not a fancy stuff (reredoxes adinfinis).

That are capabilities that progressing-processing-oriented people will never get even close to that which document(ing)-oriented people (users) transparently had and is about to get lost.

The World Wide Web, invented at CERN in 1989 by Tim Berners-Lee, is a system of interlinked hypertext _documents_ - not interlinked programs (opaque and superior to take control over any data).
