There are two possible sources of instability, the URI -> resource
mapping and the resource -> representation relationship. To be useful
in the way that Larry wants it to be (e.g. for citation), DURI has to
nail down *both* of these. The DURI names not the original resource,
but a checkpoint of the original resource - a second resource whose
representations are, and always will be, the representations that the
original resource had at the given time.

(using AWWW terminology here.)

I was just saying that the representations at a given time is a
potentially infinite set with arbitrarily varying content.
