Whoops, thanks Roy. I was in too much of a hurry.

I meant to say that you don't get a representation with a 303.

And as far as what can or cannot be inferred from a 303, this is an item
I'm hoping to get consensus on at next week's TAG F2F. As I replied to Pat
earlier, I prefer the inference the way that you and he have both
articulated it.

Best wishes
Rhys
