"id" isn't part of the spec. So, it's definitely not required, though it
probably makes sense to put it there, and most implementations that I've
seen that have such a thing will do so. However, I've always seen it as
reasonably common sense, and not worked it into the spec (though I
wouldn't have a problem with making it recommended).
