Missing ISO-3166 Alpha-2 Codes: XK, AC, and TA

[jeffward01]

Hello,

I am using this library in conjunction with https://github.com/twcclegg/libphonenumber-csharp.

You can list the supported region ISO-3166 codes, the list of codes can be found here: https://github.com/twcclegg/libphonenumber-csharp/blob/main/resources/PhoneNumberMetadata.xml

In doing so, I have discovered that (3) Regions are missing:

• Name: Ascension Island

  • Code: AC
  • Link: http://www.itu.int/oth/T02020000AF/en

• Name: Tristan da Cunha (TA)

  • Code: TA
  • Link: http://www.itu.int/oth/T02020000AF/en
  • Notes: Calling code and formatting shared with 'SH'

• Name: Kosovo

  • Code: XK
  • Link: https://www.itu.int/oth/T02020000FD/en
  • Link: http://arkep-rks.org/?cid=1,50

According to the official ISO-3166 (https://www.iso.org/obp/ui/#iso:pub:PUB500001:en),
AC and TA are considered Exceptionally reserved code elements and XK is considered User-assigned code elements.
Those entries are not part of the Officially assigned code elements list.
