Type constraint limited to classes[edit]

I hope it's ok to extend the type constraint to include also instances, not just classes, of appliances and electronic machines? I'm working on BESK (Q4384176) of which only a single instance was ever built. Also, should the property scope be set to main value only or include constraints as well? --SM5POR (talk) 03:09, 13 January 2022 (UTC)[reply]
