IMO content negotiation deals with a negotiating process between client 
and server to decide which of a limited number of versions the server 
should send to the client. The content provider is responsible for all 
of the provided versions and so should also be responsible for their 
accessibility. So a conformance claim with a URI for a negotiated 
resource must cover all possible versions of the content.

This does not cover personalized content, where the number of versions 
are unlimited (at least sort of). IMHO this is a different topic.
