The fact that the default value isn't going to pass a constraint means
that it's invalid to not provide a value or use default, yes, but I don't
agree that it's necessarily a real contradiction in the definition,
especially given that AFAIK there's no way to opt out of having a default
(apart from a construct like the one given).
