+//
+// An existing defaulter method (`SetDefaults_TYPE`) can provide the

+# OpenAPI Extensions
+OpenAPI spec can have extensions on types. To define one or more extensions on a type or its member
+add "+k8s:openapi-gen=x-kubernetes-$NAME:$VALUE" to the comment lines before type/member. A type/member can
