useDateTimeOffset	Use DateTimeOffset to model date-time properties		false
useOneOfDiscriminatorLookup	Use the discriminator's mapping in oneOf to speed up the model lookup. IMPORTANT: Validation (e.g. one and only one match in oneOf's schemas) will be skipped.		false
validatable	Generates self-validatable models.		true
