             An HTTP response MAY include multiple provenance link headers, indicating a number of different resources that are known to the responding server, each providing provenance about the accessed resource.

+            The presence of a provenance link in an HTTP response does not preclude the possibility that other publishers may offer provenance information about the same resource.  In such cases, discovery of the additional provenance information must use other means (e.g. see <a href="#third-party-services" class="sectionRef"></a>).
