I'd like to skip the population of a DOM via: for(var i in obj) { 
dom.appendChild(i);.... };

Anne has "overloaded Node.appendChild" with DOMString.
That makes appendChild('<div>hello world</div'); easier.  That's my 
understanding, anyway.

I'm trying to solve the appendChild({div: 'hello world'}); syntax that 
we were trying to address with Element.create.

I know that a JSON.toNode with XSL or other selectors could be a nice 
way of doing things in the future, similar to Microsoft's LINQ (but 

JSON is widely used, it's quite useful, and it'd be nice to have better 
integration between JSON and DOM+XML.

Using JS objects as a means of populating has been discussed repeatedly 
for use with SVG.

Having looked at this again, I'd really prefer to have something like 
Node JSON.toNode(obj) over DOMString JSON.toXML(obj).
