One relevant scenario is the use of the Etag header in HTTP/1.1. The URL+ETag (and maybe additionally mime-type) uniquely identifies a particular representation. In practice, an http: identifier is used to identify a representation dispenser, and the combination of http: identifier with ETag is used to identify a particular "bag of bits" returned by that dispenser.
