I think it's impossible, within the terms of HR14, to say 'denote(U) not a IR' -- you can prove something is in IR, but you can neither prove nor even operationally assert that it's not.

I don't think you even need the 303.

If you make a URI, declare it to be a URI identifying my home page (I think David Booth has written about how you'd do this formally), and then have it 200-respond with a map of the Englisher Garten, then this places my homepage in IR, but does not access it.  This appears to be compatible with HR14 in an only slightly perverse reading.  I'm not sure what follows from that (but I suspect that way madness lies).

I think we should draw a veil, here...
