Best Practice:B There is no single style that best handles all single
(one-part) names. Tibetan, Indian, and Burmese single namesB that are not
surnamesB may be tagged asB <given-names>; there is no need to commit the tag
abuse of calling the given name a surname. Most westernized single names
(bPeleb, bPrinceb, bBabyfaceb, bAztekb) are more likely to be
retrieved properly if they are tagged asB <surname>s.

But from Crossref:B 

The surname of an author or editor. The surname, combined with given_name,
forms the name of an author or editor. Whenever possible, the given name
should not be included in the surname element. In cases where the given name
is not clear, as may happen with non-Western names or some societies in which
surnames are not distinguished, you may place the entire name in surname

(This has come up because our platform flagged up some missing surnames when
depositing content.)
I'd be grateful for insight.
