+DEFINED BY fields
+-----------------
+
+Here is only very simple example how you can define Any/OctetString
+fields automatic decoding::
+
+    class AttributeTypeAndValue(Sequence):
+        schema = (
+            ((("type",), AttributeType(defines=("value", {
+                id_at_countryName: PrintableString(),
+                id_at_stateOrProvinceName: PrintableString(),
+                id_at_localityName: PrintableString(),
+                id_at_organizationName: PrintableString(),
+                id_at_commonName: PrintableString(),
+            }))),),
+            ("value", AttributeValue()),
+        )
+
+And when you will try to decode X.509 certificate with it, your pretty
+printer will show::
