Is "Additional information from an authoritative answer" a higher
trustworthiness sub-rank than "Additional information from
non-authoritative answers"? Or are there no sub-ranks and they have the
RFC 2181 Clarifications to the DNS Specification July 1997
5.4.1. Ranking data
The accuracy of data available is assumed from its source.
Trustworthiness shall be, in order from most to least:
+ Additional information from an authoritative answer,
Data from the authority section of a non-authoritative answer,
Additional information from non-authoritative answers.
