Andorran reference in Gibraltar story

Your story implies that Andorra received its sovereignty in 1993, but according to the CIA website, "Andorrans lived under a unique co-principality, ruled by French and Spanish leaders (from 1607 onward, the French chief of state and the Spanish bishop of Seu d'Urgell). In 1993, this feudal system was modified with the titular heads of state retained, but the government transformed into a parliamentary democracy."
