The conceptId field, the languageCode field and the
field will not change between two rows with the same id, in other words they are immutable. Where a change is required to one of these fields, then the component will be inactivated (by appending a row with the same id and the
field set to false) and a another row will be added representing a new component with a new id. Only limited changes may be made to the
term field, as defined by editorial rules.
Each
