Qualifiers that follow a person’s name, for example, “Sr.”, “Jr.”, “III”, “3rd”, etc.
The <suffix> element should be used for parts of people’s names, not for degrees such as PhD or DDS. The academic degrees are part of the information that is known about a contributor, not part of the name of the contributor. Degree and certification information may be placed directly after the person’s name:
<contributor ...> <name> <surname>Smyth-Jones</surname> <given-names>George</given-names> <suffix>Sr.</suffix> </name> <degrees>PhD</degrees> </contributor>
Or the <degrees> may be included later within the contributor element, interspersed with other types of contributor information such as the <address>, <aff>, <bio>, and <email>.
Text, numbers, or special characters.
