  • According to my reading of the [JSON Schema Spec](https://json-schema.org/draft/2020-12/json-schema-validation#name-required), the answer is **no*.* `required` array can contain elements which are not in the properties `dictionary`.
  • The example schema in question seems to be valid.
  • Semantically it means that the `cookies` property must exist for the JSON to pass validation, but it doesn't matter what type of property it is.

According to my reading of the [JSON Schema Spec](https://json-schema.org/draft/2020-12/json-schema-validation#name-required), the answer is **no**, `required` array can contain elements no in the properties `dictionary`.

Semantically it means that the `cookies` property must exist for the JSON to pass validation, but it doesn't matter what type of property it is.
