In the math/graph realm we have the domain name space and we talk about trees, subtrees, and vertices. In the DNS realm we have zones, subzones, and zonefiles and we talk about delegation, name servers, and resource records (among other things). It's useful to discuss the name space separately from the resolution protocols, but from an engineering standpoint the usefulness level is much higher if we also know how specific systems (like the DNS) use the name space - the correspondence or mapping, if you will, between the math/graph realm and the DNS (as a system of protocols) realm.

Hmm… but I thought we were discussing the syntax of the name-space. It seems that we then arrive at 3 things that all hook together: syntax, namespace, and resolution protocol.

The Internet DNS namespace is specifically defined through the resolution system starting at the IANA root. To first approximation it is the hints file used at the resolver that defines the name-space.

I lost track of the question that we are trying to answer? Ed, is there some underlying thing you want to arrive at? Do you want to arrive at a precise definition of Domain names or do you want to solve the confusion that arrives from identifiers that look like domain names?
