+        <p>The <code>WotThing</code> and <code>WotDirectory</code> endpoints allow publication of service endpoints in a DID document
+          that can be used to fetch Web of Things (WoT) Thing Descriptions (TDs).
+          The <code>WotThing</code> endpoint is a REST service that returns a TD
+          when the <code>GET</code> method is used.  
+          This can be used for self-describing devices or services, or be a service
+          separate from the actual device or service described by the TD.
+          The <code>WotDirectory</code> is also a REST service that returns a TD, but this service is always
+          a Web of Things (WoT) Thing Description Directory (TDD), and the TD returned by a <code>GET</code> always describes the TDD's interface.
+          Details (including normative statements detailing the above) are in the
+          <a href="https://www.w3.org/TR/wot-discovery/">WoT Discovery</a> specification.

         <h4>CredentialRegistry</h4>
         <p>The <code>CredentialRegistry</code> endpoint allows publication of a dedicated service endpoint in a DID document, through which verifiable credentials can be queried. Each registry endpoint is a REST endpoint. When a `GET` request is sent to the URI formed by appending the <code>credentialSubject.id</code> as a URL-encoded string to the given endpoint URI, the registry MUST return an array of verifiable credentials associated with the subject ID. A sample registry endpoint can be found <a href="https://ssi.eecc.de/api/registry/swagger/#/Credentials/get_api_registry_vcs__id_">here</a>.</p>
