Well, sure, I have no disagreement with the preceeding paragraph related to
``authority''.  (I do, however, have a *very* strong disagreement with the
assumption therein that a resource is denoted by only one URI reference.)

However, describing the knowledge published by the authority that is the
managing authority of a URI reference as ``authoritative'' is very
different in my mind from this sentiment.  To me, the use of
``authoritative'' indicates that all other knowledge is indeed `wrong' or
`less trustworthy' or `lesser quality'.  These value judgements should
not, I think, be mandated by the structure of the Semantic Web; instead
they should emerge from some other (probably social) process.
