An group of data elements which together describe a promotional event or series of event occurrences such as an author tour. Optional in any occurrence of the <PromotionDetail> composite, but it may be omitted only within a partial or ‘block update’ (Notification or update type 04, see P.1.2) when the intention is to remove all previously supplied promotional event detail. When used normally, it is repeatable to describe multiple events linked to promotion of the product.

The promotional event composite must contain at least one <EventOccurrence>. It may optionally contain one or more contributors to the event, listing those that are also contributors to the product using <ContributorReference> and those that are not contributors to the product using <Contributor>. If there are no contributors to the event of either type, an optional <NoContributor/> flag may be included instead.
