It seems that there is some notion of "absolute resource specifiers", e.g. a
specific person; and "relative resource specifiers", e.g. the person with a
login of 'champin' at Example University.  I was trying to portray that (in
the absense of statements from the publisher of the URI) it is safer to
assume URLs represent the latter.
