How to output oneOf for discriminated unions.

[justinfagnani]

For a discriminated union it would be more descriptive to use oneOf instead of anyOf. Human readers and non-TS tooling might not be able to tell that because of the interfaces it's not possible to be valid against more than one of the subschemas, so oneOf would be more clear.

Could we get some kind of annotation to put on a union to declare that it's discriminated, or is there some way to directly infer this from the TS compiler's type-checker?
