OK, so what you said earlier was that they don't have a URI until 
they have a URI. Hard to argue with that, I concede. Is that the sum 
total of this debate?

A question.  Saying "has a URI" sounds like that there has to be 
something that is doing the having. Is that right? Or could there be 
a URI which wasn't had by anything? For example
http://www.ihmc.us/users/phayes/mb#blumlum
(?)

Well, I do need to address it, as soon as possible.  But that is 
fine: I don't mean to burden y'all with my problems.

I am now at a loss how to proceed.  I thought we were talking about 
reference and existence, but apparently we were at cross purposes.

If we aren't talking about existence, could I simply ask y'all to 
please avoid the use of the word "exists" and its cognates, then, if 
you possibly could manage to do so? It is hard to imagine a word more 
likely to cause semantic problems when used casually or carelessly.

Thanks.
