Instead of introducing more interfaces (which don't have additional 
functionality), and instead of introducing Element.create, I would 
rather see a pattern like:

   var e = new Element("div", ...);

There is no requirement that the object returned from a constructor be 
an object that has the constructor.prototype as its [[Prototype]], so 
having the above constructor return an HTMLDivElement is fine.

(Also note that the constructor text nodes should be Text rather than 
TextNode, according to the interface name in DOM Core.)
