From RFC4519: "The sn (surname in X.500) attribute type contains name strings for the family names of a person."
From eduPerson: "If the person has a multi-part surname (whether hyphenated or not), store both 1) the whole surname including hyphens if present and 2) each component of a hyphenated surname as a separate value in this multi-valued attribute. That yields the best results for the broadest range of clients doing name searches."
In SWITCHaai, home organizations MUST provide a single value only: the surname which is used for official communication with that person.
