Usage/Remarks

Best Practice

Although this attribute is optional and open to any value, for best practice, the country code should be provided whenever it is known, and the ISO 3166-1 2-letter alphabetic codes should be used, for example:
US
United States
GB
United Kingdom
CA
Canada
The complete list is available from ISO, in HTML, text-file, and XML-file versions at the following location: https://www.iso.org/obp/ui/#search (choose the country code button and search using the search icon).
On the element <country>, archives and publishers can use this attribute to regularize the input for searching without altering the element content, for example, placing a country code in the attribute when the <country> element content is fully spelled out or uses a non-standard country abbreviation.
