optional, single

ref=unique identifier of the dive trip to be cross-referenced — compulsory

Via <tripmembership> the dive trip can be indicated during which the dive was made. Because the <profiledata> section (where all dive data are stored) comes before the <divetrip> section — so that a cross-referencing is possible on dive data — in the UDDF file, it is not possible to cross-reference a <trip> within a <dive> element. Therefore, the <tripmembership> element allows for an assignment of a dive to trip.
