Slight aside: what are the performance impacts here? I've been wondering for a while whether JSX is a little dangerous in that it makes repeated, huge, nested calls to React.createElement() look like plaintext. For example, I could easily just run element.innerHTML = "<svg...>" to add SVG content to my page. If the SVG isn't being dynamically updated, doesn't making JSX like this incur a large and unnecessary overhead?
