Qualifiers that follow a person’s name (for example, Sr., Jr., III, 3rd).
Best Practice: The <suffix> element should be used for parts of people’s names, not for degrees, such as Ph.D. or DDS. The academic degrees are part of the information that is known about a contributor, not part of the name of the contributor, and should take the <degrees> element. Degree and certification information may be placed directly following the person’s name within the contributor information:
<contributor ...>
<name>
<surname>Smyth-Jones</surname>
<given-names>George</given-names>
<suffix>Sr.</suffix>
</name>
<degrees>PhD</degrees>
</contributor>
