Updating Amos' proposal with Martin's suggestion, and downgrading from SHOULD to MAY leaves us with:

> If multiple selected responses are available, the cache will need to choose
> one to use. When a selecting header has a known mechanism for doing so
> (e.g., qvalues on Accept and similar request headers), that mechanism MAY
> be used to select preferred responses; of the remainder, the most recent
> response (as determined by the Date header field) is used, as per Section 4.

Does that work for everyone?
