     Return a serializable representation of the templated field.
 
-    If ``templated_field`` is provided via a callable, compute MD5 hash of source
-    and return following serialized value: ``<callable fingerprint(MD5) hash_value``
+    If ``templated_field`` is provided via a callable then
+    return the following serialized value: ``<callable full_qualified_name>``
 
     If ``templated_field`` contains a class or instance that requires recursive
     templating, store them as strings. Otherwise simply return the field as-is.
