 A root server identifier is the DNS name for a root server operator that appears in the root zone and root hints file.

Strictly speaking, a root server identifier is not a name "for" an RSO; it is a name associated with an RSO. So how about:

root server identifier
A root server identifier is the DNS name associated with a root server operator that appears in the root zone and root hints file.

 Personally, I'm not ready to give up on location/site as part of the RSSAC
 definition for instance.  When we're at an RSSAC meeting discussing
 instances, location is the primary way we identify them. I really liked the
 plain language Wes used in his recent definitions and i'm concerned your
 more technically accurate definition will confuse much of our RSSAC
 audience.
 
 If folks really like "site", we could go back to something close to Wes' original wording ("...that serves root data from a particular site...") with:
   A root server instance is the portion of a root server operator's infrastructure
   that serves root data at one site using one of the IP addresses associated with
   a root server identifier.

I am sympathetic to the need to include a notion of topological location in the definition of instance: I don't think there's a way around it. How about we simply (he writes, hopefully) qualify "site" as topological location:

I know "i.e." is a bit clunky (Paul Hoffman consistently tries to remove it when editing my writing), but I think it serves a good purpose here.
