Fine, and I apologize for my terminological slip. 
But my main point remains. Most names are not 
identifiers in the sense required: they are not 
completely unambiguous, they do not have a single 
referent, and they are routinely used in 
situations where to determine the intended 
meaning even well enough for pragmatic adequacy 
requires negotiation or the use of context. So if 
URIs are just a prescription for encoding names, 
then either what is said about URIs is wrong, or 
URIs have some how magically re-defined the 
general business of naming things. I lean towards 
the former conclusion.
