Template:YYYY in nationality motorsport category header/doc

Use this to create a category of the form "YYYY in nationality motorsport", where YYYY is a 4-digit year

e.g.
 * Category:1997 in French motorsport
 * Category:2011 in Mexican motorsport

Normal usage
The normal usage requires no parameters, because the template looks up the other data.

e.g. on Category:1967 in Australian motorsport, no parameters are needed

The other needed data is:
 * 1) the adjectival form of the country in which the country is located. This is looked up by Template:GetAdjectiveFromCountryName

If either of those lookups fails, then an error is reported unless the required data is supplied by an optional parameter.

That may be due to this category being misnamed, or it may be due to an omission in the lookup table used by Template:GetAdjectiveFromCountryName. (Some former countries may have been omitted. Also, when country has been renamed, the lookup uses only the current country name).

If a lookup fails, then the template creates no output other than an error message. If you are satisfied that the category is correctly named, use the one of the optional parameters below.

Optional parameters
e.g. on Category:1989 in West German motorsport, use
 * Fooish bypasses the lookup of the nationality, and uses "Fooish"
 * AnotherCountry is available for use when a country is part of another country.
 * yes turns on diagnostics, which may help if the template doesn't work as expected

Tracking
Use of the parentnationality parameter is tracked in:
 * Category:Template YYYY in nationality motorsport category header with parentnationality (population )

Categories where country lookup fails are tracked in a category shared with many other templates:
 * Category:Errors reported by other category header templates (population )
