contenteditable browser support, does it work in browsers that doesn't support html5

Question

I read that contenteditable is new in HTML5 and in list of browser support for contenteditable shows that IE 5.5+ supports it.

I just got confused. as far as I know IE6 for instance doesn't support HTML5. if its new in HTML5 how is it possible that IE6 supports it. If it doesn't work in lower versions of IE then how does it support it?

Answer 1

It's not new in HTML5, it's just been standardized by the WHATWG.
