Template:Fooian fooers/doc

Displays standardized category navigation for occupations and nationalities, required by Naming conventions (categories).

Adds a pair of standard parent categories:
 * Profession
 * Nationality

If the "Supercategory" parameter is used, the following categories will be generated instead:
 * Profession
 * Nationality

Self-checking
The template tests for the existence of  Category:Profession by nationality  or  Category:Supercategory by nationality , and alters its output as follows:


 * 1) If the "Supercategory" parameter is supplied, but Category:Supercategory by nationality  does not exist, then  Category:Supercategory  will be used instead)
 * 2) When the "Supercategory" parameter is not supplied, the template tests for the existence of Category:Profession by nationality  . If that does not exist, then  Category:Profession  will be used instead)
