would be also nice to add your schema to test schemas - https://github.com/fsprojects/SwaggerProvider/tree/master/tests/SwaggerProvider.ProviderTests/Schemas/v3

and add test like this https://github.com/fsprojects/SwaggerProvider/blob/master/tests/SwaggerProvider.ProviderTests/v3/Swagger.I0173.Tests.fs to check that TP works on this schema and manually check return type before merge/release

[jkone27]

added a sample and tests, thanks!
