I had this error this morning. I had XML which looked like this:







: : : :

etc.

When XSD was creating classes, it was creating a class for Constraint, but
not using it in ConstraintList. Where you might expect "private Consraint
constraintField", instead it was creating "private Test[][] constraintField".
I kinda see where it was coming from, but it wasn't serializing.

For reasons I haven't bothered to try to understand at the moment, changing
the .cs file manually to that it was simply "private Test[] constraintField"
(and changing the accompaning property as well) meant that it serialized
fine. It certainly looked alright after a superficial examination of my
classes in the debugger.

Anyhow, I didn't want to be having to manually edit the .cs everytime I
regenerated it so I added a dummy attribute to Constraint. As I suspected,
was enough to make XSD behave and create the classes as I'd expect
(ConstraintList now has "private Constraint[] constraintField).

Hope this is some help to someone.
