That's the point Ralph is making. Some elements may change before the specification is finished, so until the final version is completed, nobody can answer that question with certainty. Yes, you can use HTML5 with Modernizr, but that relies on Javascript, and you have no control over whether the person using your site has Javascript enabled or not. So why choose a design method that includes so many uncertainties, when HTML4 is fully supported by all modern browsers?
