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.
