+<ul>
+<li>When applied on a Gateway, you can also use the special header name <code>x-jwt-claim</code> for matching JWT claims in
+the VirtualService. Claims of type string or list of string are supported and nested claims are also supported using
+<code>.</code> as a separator for claim names. Examples: <code>x-jwt-claim.admin</code> matches the claim &ldquo;admin&rdquo; and <code>x-jwt-claim.group.id</code>
+matches the nested claims &ldquo;group&rdquo; and &ldquo;id&rdquo;.</li>
+</ul>
+
+<p>The following example creates the request authentication and authorization policies for JWT validation on ingress
+gateway and routes requests based on the &ldquo;version&rdquo; claim in the validated JWT.</p>
