Single value constraint invalid ?

As the external database « Mémoire des Hommes » has evolved to an agglomeration of multiple War Dead subdatabases, a person may be filed under several identifiers in each relevant subdatabase. (Just encountered this case with Charles Vuillemin listed with 3 different identifiers for « Morts en Déportation », « Fusillés du Mont-Valérien », « Sépultures de guerre », or Honoré d'Estienne d'Orves). Is there any objection to lifting the "Single value" constraint? --FoeNyx (talk) 12:35, 15 July 2021 (UTC)
