The Link Object represents a possible design-time link for a response.
The presence of a link does not guarantee the caller's ability to successfully invoke it, rather it provides a known relationship and traversal mechanism between responses and other operations.

Unlike _dynamic_ links (i.e. links provided **in** the response payload), the OAS linking mechanism does not require link information in the runtime response.

To support polymorphism, the OpenAPI Specification adds the [`discriminator`](#schemaDiscriminator) field.
When used, the `discriminator` indicates the name of the property that hints which schema definition is expected to validate the structure of the model.
As such, the `discriminator` field MUST be a required field.
There are two ways to define the value of a discriminator for an inheriting instance.
- Use the schema name.
- [Override the schema name](#discriminatorMapping) by overriding the property with a new value. If a new value exists, this takes precedence over the schema name.
