Ordered component reference set can be used to create a simple ordered list of components, i.e. a list that do not include any nesting, or groups. It can for example be used to prioritize the sort order of the descriptions with identical terms when they are displayed. It can also be used to specify the order of descriptions displayed in a simple pick list.
