        Clients SHOULD use this as a guide when using content repository endpoints.
        All values are intentionally left optional. Clients SHOULD follow
        the advice given in the field description when the field is not available.

        **NOTE:** Both clients and server administrators should be aware that proxies
        between the client and the server may affect the apparent behaviour of content
        repository APIs, for example, proxies may enforce a lower upload size limit
        than is advertised by the server on this endpoint.
