John had a remark about what "host name" means. I just had a very
cursory look, but I don't see a definition of host name or a reference
to the relevant RFCs. There's nothing in the above that decides
whether a given string is in fact a host name, as far as I can tell.
That might be ok; I don't know.
So what _is_ "host name" supposed to mean in the above? Is this the
same as host name in RFC 952 as modified by RFC 1123?
I'd also suggest that you make a request to the DNS Directorate for a
review (you're likely to get one anyway, but this way you get in the
queue early).
