I don't think I was clear - this is only about the DNS protocol. This document proposes that the DNS protocol behave differently depending on the data being carried (QNAME) in it's own messages. (I.e., the rule could be stated: if the QNAME is a single label, then if the QTYPE is NSEC the NSEC can be used to assemble other NXDOMAIN responses. This assumes the root zone owns only single label names [and is DNSSEC signed with NSEC], which might not be true for all root zones.) This isn't about processing different values differently, this is about changing the behavior of the protocol based on environmental factors.
