like in australia, they dont say wales when they mean new south wales do they. (Do they? No right?)
the constituent countries are: the Netherlands, Aruba, Curacao and sint Maarten. The special municipalities are Bonaire, Saba and st Eustatius.
So if you would have said it is like Curacao and the Netherlands. Your example wouldnt have been completely off (cause it is now).
maybe he should ve said symbol instead of coat of arms, but that would open a whole other can of worms..
