+
+        <p>
+One of the core use cases for this specification is the ability to present a
+different rendering payload based on the preferred language or locale of the
+user. This extends beyond the value-level localization offered by the core
+[[VC-DATA-MODEL#internationalization-considerations]] specification, and beyond
+translating field labels. Clients displaying or rendering VCs must be able to
+select arbitrary layouts, styling or full pre-rendered payloads based on the
+user's language and locale preferences.
+        </p>
+
+        <p>
+In the example below, the `renderMethod` property contains an array of two
+`static` render method objects, each providing a pre-rendered PNG image of
+the credential. The client selects the one whose `inLanguage` value best
+matches the user's language preference.
