2.2 Single National Code Retirement
Where one or more National Codes within an Attribute are to be retired, but the Attribute itself remains active, a different process is undertaken. In this case, the codes are ‘greyed out’ and notation added as to the date of their retirement. This date aligns to the implementation date of the associated Information Standard and Collection (including Extraction).
