People have talked about "1:1 relationships" between URIs and resources.
The term "1:1" is ambiguous (see my previous posting) but is susceptible
of being interpreted as meaning "bi-unique".

Also, it seems to me that "http://www.reutershealth.com/scritchifchisted"
does not represent a resource, and that I have the authority to say so.

Heh heh... that is indeed the case at present, as ftp.unicode.org is broken.
However, the *intent* of the Unicode Consortium is that they are the same
in every respect.

Just so.

That depends.  If there is no discoverable evidence that Wen Lee is guilty
of espionage, then it would be sound to conclude (provisionally) that he is
not a spy.  Or so thought the judge.
