+        <p>
+           Following [[RFC9110]], services SHOULD use the <code>Accept-Language</code> header to let clients select the language in which user-facing text is returned.
+           They SHOULD use the <code>Content-Language</code> in their responses to expose the language each response is returned in.
+        </p>
+        <p>
+          Examples of user-facing text in service responses are: the name of the service and the name of property configuration fields in the manifest, the name and description of entities, types and properties,
+          the contents of the entity preview pages, and the documentation linked in the manifest.
