"content-address*ed*" derivation is misleading because all derivations are *themselves* content-addressed. What may or may not be content-addressed is not derivation itself, but the *output* of the derivation. The outputs are not *part* of the derivation (for then the derivation wouldn't be complete before we built it) but rather separate entities produced by the derivation. "content-adddress*ed*" is not correctly because it can only describe what the derivation *is*, and that is not what we are trying to do. "content-address*ing*" is correct because it describes what the derivation *does* --- it produces content-addressed data.
