Or are you saying that we have both an > internal database ID and an external database ID? yeah, i thought about this and went ahead with an inclusion of (a) anyway; think we don't need to specify any internal DB handles, but we do need a way to communicate across external database boundaries. I concede that if we define the fingerprint for use as an *external* DB handle, it's entirely likely (and reasonable) for implementers to use it as an internal DB handle as well, but i don't think we need to specify it as a target use case. If we say that use case (a) isn't a motivating use case for the fingerprint, do we have a story to tell about how an implementation might retrieve a specific key from an external database? or do we not need to tell that story? --dkg
