How about a slight recasting of that:

1. Different URIs can identify the same resource, in the opinion of the 
creators and users of that resource.
2. The Web is designed on the principle that a single URI identifies a 
single resource which does not change.  In practice, this principle is 
someties violated (insert list of nasty examples), and software must 
often deal with the consequences, but such inconsistency is always 
damaging and SHOULD be avoided.  -Tim
