Where OpenAPI tooling renders rich text it MUST support, at a minimum, markdown syntax as described by [CommonMark 0.27](https://spec.commonmark.org/0.27/). Tooling MAY choose to ignore some CommonMark features to address security concerns.

Relative references used in `$ref` are processed as per [JSON Reference](https://tools.ietf.org/html/draft-pbryan-zyp-json-ref-03), using the URL of the current document as the base URI. See also the [Reference Object](#referenceObject).
Relative references in [`Schema Objects`](#schemaObject), including any that appear as `$id` values, use the nearest parent `$id` as a Base URI, as described by [JSON Schema Specification Draft 2019-09](https://json-schema.org/draft/2019-09/json-schema-core.html). If no parent schema contains an `$id`, then the Base URI is determined as in the previous paragraph.

A simple object to allow referencing other components in the specification, internally and externally.

The Reference Object is defined by [JSON Reference](https://tools.ietf.org/html/draft-pbryan-zyp-json-ref-03) and follows the same structure, behavior and rules.

For this specification, reference resolution is accomplished as defined by the JSON Reference specification and not by the JSON Schema specification.

This object cannot be extended with additional properties and any properties added SHALL be ignored.

Note that this restriction on additional properties is a difference between Reference Objects and [`Schema Objects`](#schemaObject) that contain a `$ref` keyword.
