::::I can live with this current variant, but since UK parliament did enact SoW, the date does apply. Please note that the table/date does not read "since when" anywhere, hence my original request - and that would likely be ambiguous also, since they were arguably realms/dominions/whatever before with slightly different status. Simplest would be to avoid the question of what "since when" means and limit future discussion/argument about the nuances of "realminess" by having fact that cannot be disputed. Would anyone object to having 1931 in the box, but with a footnote saying that, as realm from which others gained independence, not applicable to UK internal governance? This would clarify that UK also enacted Westminster and should be unassailable internal logic.
