Purpose

An  allows a collection of to be defined with a specified order. This type of is therefore useful for creating ordered lists and to specify groups where the components that belong to the same group share the same order.

Data structure

An is an Integer is used to represent ordered lists and alternative hierarchies. Its structure is shown in the following table.


Ordered component reference set - Data structure


Metadata

The following metadata in the "Foundation metadata " supports this :
