 Notary v2 requires Payload to be the content **descriptor** of the subject manifest that is being signed.
 
 1. Descriptor MUST contain `mediaType`, `digest`, `size` fields.
-1. Descriptor MAY contain `annotations` and if present it MUST follow the [annotation rules](https://github.com/opencontainers/image-spec/blob/main/annotations.md#rules).
-   In Notary v2 annotations are being used to store signed attributes.
-   The annotations key prefix for Notary v2 use is not yet finalized.

+1. Descriptor MAY contain `annotations` and if present it MUST follow the [annotation rules](https://github.com/opencontainers/image-spec/blob/main/annotations.md#rules). Notary v2 uses annotations for storing both Notary specific and user defined signed attributes. The prefix `org.cncf.notary` in annotation keys is reserved for use in Notary v2 and MUST NOT be used outside this specification.
 1. Descriptor MAY contain `artifactType` field for artifact manifests, or the `config.mediaType` for `oci.image` based manifests.
 
 Examples:
 
 ```jsonc
 {
-    "mediaType": "application/vnd.oci.image.manifest.v1+json",
