Version Notes: Can be used to inform reference set consumers on the areas of focus for that version.
ECL Definition: Available for Intensional reference sets only.
NOTE: There are three sets of metadata per reference set: Immutable, versioned, and non-versioned. A reference set’s immutable content, such as the field SNOMED Id, cannot ever change once the value is defined. Versioned metadata fields may change per publication of the reference set. An example of this is the Version Notes field which has unique content per published version. Finally, non-versioned content may change at any point, but the change is tied to the reference set itself rather than a version. An example of this is the reference set Narrative metadata field.
