The Operator-name attribute originates from the GSM operator WLAN roaming
community. They have great interest to reuse current existing GSM/GPRS roaming
billing model & systems -- that are rather huge these days. In that context
TADIG code is important as it is used to identify operators, roaming partners
and such for roaming billing.
There are similar things for e.g. CDMA roaming. I'm currently digging it
out (I don't really have too much knowledge about CIBER based roaming

Agree. I could(?) write a bit text for that. Unfortunately the publicy
issue of these roaming specs and procedures is somewhat out of our hands.
Those specs are usually freely usable etc but just not too easily reachable
for organizations outside the operator camp.
