I believe that one would work, because:
"The type none matches no values. none is the identity for choice, that is
(Type | none) = Type."(2.4.3 Content models)
So, I think the static type of the operand is the static type of (1 div $x).
Therefore, I think this would not yield a type error:
zero-or-one((error(), 1))
I can't deny nor confirm that zero-or-one(error()) is a type error, but if it
is, it could be because there is no rule that lets 'none' match an arbitrary
type, perhaps.. Though, I also think it would make sense that it is not a type
error.
But I am neither a static typing guy; I've mailed Jérôme to see if he can have
a look at this report.
