What's the difference between person name formats and person name styles?
Person name formats determine the order of the person name components for a specific format type.
The sequence of components for predefined name format types can be configured for a country. For example: Display Name can be defined as First Name, Last Name, and List Name can be defined as Last Name, First Name.
Person name styles define the person name components that can be captured for a country; for example, first name, last name, title, previous last name, known as, and so on. Person name styles can be configured by selecting the required name components for a country.
