      A list of valid current currencies according to ISO 4217.

      The list was obtained from https://www.six-group.com/en/products-services/financial-information/data-standards.html#scrollTo=isin

          The decimal positions that lead to this currency smallest unit.

          For example: since Japanese Yen (JPY) have no cents, this value is 0.

          On the other hand, since the US Dollar (USD) is composed of cents, and each dollar equals 100 cent, this value is 2.

          To convert from normal unit (Dollar) to smallest unit (Cent), multiply by `10^decimal_positions`.
          To convert from smallest unit (Cent) to normal unit (Dollar), divide by `10^decimal_positions`.

    description: |
      A list of applicable VAT rates for guest services, by country.

      The list was provided by the Finance team. A value of 0% does not 
      necessarily mean that the country doesn't have VAT, but rather that we 
      don't need to charge it to guests from that country.

      Country names and codes _almost_ follow ISO 3166-1 (https://en.wikipedia.org/wiki/ISO_3166-1).
      The only exception sits in the Kosovo record. Kosovo does not appear as a country in ISO 3166, but is nevertheless
      a valid country in the `Country` table of the Superhog backend database. Because of this, we need to include it.
      The present codes are made up (not truly ISO 3166 codes) and match the ones present in the backend.
