 Relative URI references are resolved using the appropriate base URI, which MUST be determined in accordance with [[RFC3986]] [Section 5.1.1 – 5.1.4](https://tools.ietf.org/html/rfc3986#section-5.1.1).
 RFC3986 Section 5.1.1 requires determining the base URI from within a resource's contents, which for the OAS means the `$self` field of the [OpenAPI Object](#openapi-object) for an [OpenAPI Document](#openapi-document), or the `$id` JSON Schema keyword in [Schema Objects](#schema-object).
-Within an OpenAPI Document, a Schema Object that does not have its base URI set by `$id` uses `$self` the same as any other Object, treating the OpenAPI Document as the "encapsulating entity" in accordance with RFC3986 Section 5.1.2.
+Within an OpenAPI Document, a Schema Object that does not have its base URI set by `$id` takes its base URI from the OpenAPI Object's `$self` field the same as any other Object, treating the OpenAPI Document as the "encapsulating entity" in accordance with RFC3986 Section 5.1.2.
 See [JSON Schema draft 2020-12 Section 8.2](https://www.ietf.org/archive/id/draft-bhutton-json-schema-01.html#section-8.2) for more information about base URIs in Schema Objects.
 
 The most common base URI source in the absence of `$self` or `$id` is the retrieval URI, in accordance with RFC3986 Section 5.1.3.
