Guidance for Artifacts Authors

Content other than OCI container images MAY be packaged using the image manifest. When this is done, the config.mediaType value should not be a known OCI image config media type. Historically, due to registry limitations, some tools have created non-OCI conformant artifacts using the application/vnd.oci.image.config.v1+json value for config.mediaType and values specific to the artifact in layer[*].mediaType. Implementation details and examples are provided in the image manifest specification.
