Guidelines for applying content designators:

The content designators identify the subelements occurring in a name or name/title heading that contains a personal name constructed according to the generally accepted cataloging and thesaurus-building rules [e.g., Anglo-American Cataloguing Rules (AACR 2), Library of Congress Subject Headings (LCSH)].

Personal names used in phrase subject headings (e.g., John, the Baptist, Saint, in the Koran) are contained in the X50 fields.
