In some cases, an implementer may need to add additional information about each member of a subset. This information may be additional textual information or additional coded values.
Annotating each member of a subset with additional information can facilitate the processing of subset members and assist in meeting the functional requirements of a system.
|Requirement||Description||Example Use||Reference Set|

A set of concepts, descriptions or relationships each annotated with a free text note
|Displaying a textual note for each concept in a list. For example, displaying an advisory note on how to request a particular procedure.||Annotation reference set|
|A set of components with coded annotations|
A set of concepts, descriptions or relationships each annotated with a reference to another component
|Marking each concept with a specific coded value to support automated processing of a list. For example, marking each inactive concept with a code that indicates the reason they were inactivated|
|Specifying whether descriptions are preferred or acceptable in a given dialect, care setting or clinical context.||Language reference set|
