+      Kubernetes Namespaces are an optional feature that provide a way to segment and
+      isolate cluster resources across multiple applications and users. As a best
+      practice, workloads should be isolated with Namespaces. Namespaces should be required
+      and the default (empty) Namespace should not be used. This policy validates that Pods
+      specify a Namespace name other than `default`. Rule auto-generation is disabled here
+      due to Pod controllers need to specify the `namespace` field under the top-level `metadata`
+      object and not at the Pod template level.
