x-jsonschema-unevaluatedProperties - The JSON Schema unevaluatedProperties keyword, used when targeting OpenAPI versions that do not directly support it.

JSON Schema 2019-09 introduced the unevaluatedProperties keyword to apply a schema to object properties not already evaluated by adjacent keywords.

The x-jsonschema-unevaluatedProperties extension mirrors the JSON Schema unevaluatedProperties keyword by serializing it as x-jsonschema-unevaluatedProperties when targeting OpenAPI versions where unevaluatedProperties is not directly available.

Use this extension only with JSON Schema versions before 2019-09; 2019-09 and later define unevaluatedProperties directly.

It can appear as a property in the following objects: ["Schema Object"].
