Which is why I think the 'faithfully represent' 
criterion is incorrect. I think it was meant to 
capture a case like the HTML case, where what is 
transmitted is pretty much an exact copy of the 
resource itself, but to be generalized to cases 
like scripted HTML, a reduced image, a webcam or 
a clock, etc.. ; but that cases like numbers and 
RDF graphs are in fact counterexamples which show 
that the criterion as stated isn't in fact 
adequate to capture the intended intuitions. 
Certainly a number is *not* something that can be 
rationally thought of as being at the end of an 
HTTP protocol, or that can have operations 
performed on it by a POST.
