May 31, 2013 at 1:52 comment added Will Sawin If $X\to Y$ is a flat projective morphism, we obtain a morphism from $Y$ to some Hilbert scheme. One should presumably take the discriminant divisor to be the pullback of the singular locus from the Hilbert scheme, as long as that is actually a divisor.
