No I am saying that a host name is necessarily also a domain name, seems
to be that point of the dispute.

You mean like physics.ubc.ca which is a host name and
info.physics.ubc.ca which is also a host name. 

I am willing to accept that physics.ubc.ca is both a hostname and a
domain name, but info.physics.ubc.ca is a host name only. The
interpretation of RFC1034 appears to be that info.physics.ubc.ca is also
a domain name. Not can be, but is.
