Related Items
You can use the RelatedItems response group in an
ItemLookup request to return a list of related items. You must use
the RelationshipType parameter in the request to specify the
relationship between the related items. If you have more than ten related items, use
the RelatedItemPage parameter to return the next set of ten items. For
example, a value of 2 returns the second set of ten related items.
