2.8 Ordered Collection
Some properties have a type defined as an ‘Ordered Collection of’ some type, or a list of types. For example, Member Node Information Item (4.3) has a [values] property, whose type is defined as ‘Ordered collection of information items; each item may be either an Object Node Information Item, or a Text Node Information Item’. Such properties may contain any number of values of the type or types in question. The values are strictly ordered. Ordered collections may contain duplicates, e.g. the second and fourth item in an ordered collection may be the same value. An ordered collection may be empty.
