    public abstract class ItemsEnding
    extends SystemFunction
    This class supports the two extension functions saxon:items-until and saxon:items-before, also available as experimental XPath 4.0 functions in the fn namespace. These functions take two arguments: the first is a sequence of items, the second is a function used as a predicate to determine the last item to be included in the result. The functions differ in whether the matching item is included in the result or not.
