country identifier is the common name of the country (e.g. "United States"), a common alias (e.g. "US"), or a standard country code such as those listed at ISO 3166-1 alpha-3
variant is an optional second parameter that can be used to display a flag variation, such as a historical flag. The list of variants for each country is documented on the appropriate template page, such as Template:Country data Germany
