Ah, the html equivalent of @supports, coming soon to a stylesheet near you. Or to MSIE 35, whichever is later.
Although, come to think of it, CSS doesn't come with a version declaration. And, conversely, my browser has no objection to <wbr> dropped into the middle of an HTML 4.01 document. The validator yes; the browser no.
