OpenAPI

Configuration for OpenAPI 3.x compatibility:

• respectDefaultPresence = true - respect default values when available

• requireNullableFields = false - nullable fields are optional

• useUnionTypes = false - use nullable field instead of union types

• useNullableField = true - emit "nullable": true for OpenAPI

• includeDiscriminator = true - include discriminator for polymorphic types

Use this when generating schemas for OpenAPI 3.x specifications. OpenAPI 3.x uses a subset of JSON Schema with some extensions.
