>Members of the Royal Family who hold the title of His/Her Royal Highness (HRH) and/or are a Prince or Princess generally do not use a surname in formal settings.
'Surname' = LEGAL NAME = LEGAL FICTION = PERSON = 'BODY CORPORATE'
'Royals' give themselves 'Titles' to imply a Living Status instead of referring to themselves as a 'PERSON'
