This is an update for the Iceland definition. This update uses the league structure used in Iceland for the 2019 season.
All team names used in this definition are real team names, as used for the 2019/20 season and any reserve/B teams have been removed, in which case a league would run with a smaller number of teams. The reason reserve/B teams are removed is that where leagues allow reserve/B teams to compete there is usually a block on those teams being promoted above a certain level and forbids those teams from it's national cup.
