// Discriminator is only used by OpenAPI 3+ documents, it represents a polymorphic discriminator used for schemas

// When request bodies or response payloads may be one of a number of different schemas, a discriminator object can be
// used to aid in serialization, deserialization, and validation. The discriminator is a specific object in a schema
// which is used to inform the consumer of the document of an alternative schema based on the value associated with it.

// When using the discriminator, inline schemas will not be considered.
