So rather than continue on the basis of mere innuendo, why doesn’t someone post copies of the primary material?
The edition of Annex 13 at the link in TW’s post covers amendments 1 to 10 inclusive. The current edition has 3 more: 11, 12 and 13.
What did amendments 11, 12 and 13 to Annex 13 actually say, and when did each of those amendments actually take effect?
(Nobody would be silly enough to mistake the date of an edition for the date of effect of the various amendments, would they….?)
