[gnso-rds-pdp-wg] Proposed Definition/Background for Authoritative

The phrase "Registries exist to be authoritative repositories of data"
needs to be carved in stone over the entrance to these rds discussion.
* Being simple minded, the tasks here are: "what data" and "access
under what terms". The complexities around those two tasks are the
core work of this rds-wg.
* Issues of accuracy are (operationally) a Registrar-Registry issue.
They have to be addressed at that level. Registries depend on
Registrars for the primary data from domain name registrants.
o ICANN and this wg may have views on how issues of accuracy are
addressed but that is a supplementary issue, and not the core
issue here.
....my two cents here....as a registrant
