The surname of a person
If there is only one name, for example, “Cher” or “Pele”, that is considered to be a surname for consistency purposes. This is more accurate than using <string-name> because the single name acts as a surname for identification purposes.
Conversion Note: The <name> is one of the few in these DTDs to require a specific element sequence. The idea was that names would be converted to this sequence during import conversion. If the name parts are unknown or untagged, put the whole name within the <string-name> element (<string-name>), for example, <string-name>Prince Charles</string-name>. It is better practice to use the <string-name> element than merely leaving the person’s name untagged. (The <string-name> model permits the tagging of name parts within it, so, for example, a <surname> could be tagged within a <string-name>. See Remarks for <string-name>.)
