It's the process of stringifying an existing JS object structure that's motivating this discussion.

It's much more natural to program and manipulate a JS object than a string.

These examples are using strings, but in the real world, we're using variables and method calls. It's more efficient for the coder and the implementation to go from JS object to DOM than to have a middle step of JS to XML DOMString to DOM.
