Inside the <diver> section all known data of the <owner> of the UDDF file, and the dive buddies (<buddy>) respectively, are stored.
While only one <owner> is possible, as many as necessary <buddy> elements can appear inside the <diver> section. Here <owner> is the first element to be given, thereafter all <buddy> elements.
Normally, the <diver> section must be given in an UDDF file — for the data of its <owner> (, and his/her dive <buddy>s) are stored with subsequent profile data. The only exception from this rule is an UDDF file which is used to set data on a dive computer. In this case the <diver> section can be omitted — as long as a person's data are not to be transferred to the divecomputer.
