I'm less comfortable -- I was trying an informal test
to distinguish information resources along the following lines:

  Being an information resource or not is _not_ determined by what its
  *presentation* is _about_ (*depicts* or *describes*).  'Moby Dick'
  is, after all, _about_ a ship, a number of men, a whale. . .  But it
  _is_ a novel by Herman Melville.  The Oaxaca weather report is
  _about_ the weather in Oaxaca, but it _is_ a forecast.  The HTML
  spec is _about_ rendering semantics, markup, ... but it _is_ a
  specification.

  So in a mixture of AWWW-speak and linguistic philosophy, what (an
  information resource) URI *identifies* is distinct from what it's
  _about_.

  Whereas insofar as (on the httpRange-14 'resolution' view) I
  understand the situation, if you can retrieve (via the 303 route)
  something from a non-information resource URI, what you get _does_
  describe/depict the very thing that the resource identifies.

  So for instance, presuming he moved the page and installed the
  redirect, http://www.ihmc.us/users/phayes/PatHayes.html both
  identifies and describes Pat himself.

But on that account a namespace URI is pretty clearly _not_ an
information resource. . .

I don't (yet) find "exhaustably expressible in a message" a very
useful test -- consider e.g. the number three -- I'm pretty sure I
could give a pretty thorough expression of what 'three' is all about
in a message. . .
