We very careful referred to the *operators* of the software in the draft, not the implementors. The intention is that software operators can define rules in their configuration files such that *they* determine which values have what meaning. Just like how a BGP router can use BGP communities within routing policy maps. In the load-balancer case, they might decide to use a few bits to select one of several RPZ feeds, or perhaps a view, without having to pass the client IP for the use a "source match" ACL to the backend. They might decide to use another bit to indicate that the client is trusted such that the server doesn't need to apply RRL. Granted this will need some form of representation in whatever configuration syntax is in use, but that would be implementation dependent. The minimal implementation would just need to be able to test "tag & mask == value". Ray
