variable_object

Describes validation rules for a field that can contain different kinds of objects. The value of the selector field (product_type in the example) chooses the set of rules.

Error codes: the errors of the nested rules, or FORMAT_ERROR if the value is not an object, or the selector field is missing or has an unknown value.
