1) name
The section following "Here are the general rules used for choosing
location names,
in decreasing order of importance:" talks about locations, using
"name" is inconsistent.
2) ISO-3166 code
https://en.wikipedia.org/wiki/ISO_3166
leads to
https://en.wikipedia.org/wiki/ISO_3166-1
https://en.wikipedia.org/wiki/ISO_3166-2
https://en.wikipedia.org/wiki/ISO_3166-3
There are two standards containing the string ISO 3166-1, the one
published the latest is
ISO 3166-1:2006
http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=39719
The other is
ISO 3166-1:1997
http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=24591
The ISO website also shows
ISO 3166:1981
ISO 3166:1988
ISO 3166:1993
ISO 3166-1:2006 includes three sets of codes.
There is no 1:1:1 correspondence between the sets. Not even 1:1
between any pair of them.
The Wikipedia article says:
"The first edition of ISO 3166 was published in 1974, which included
only alphabetic country codes."
Thus even the cutoff 1970-01-01 marks a time that is before the first
publication of any ISO 3166 standard.
There are at least two pairs, namely DD/DE and YD/YE where there is
not "at least one name per ISO-3166 code" but only one per pair.
When looking at the locations or location names, it follows that
"There should typically be at least one name per ISO-3166 code." was
never applied.
