+  * define an __init__ method which sets the _schedule member to None or a
+    weakref to a Schedule
+  * Set the _TABLE_NAME class variable to a name such as 'stops', 'agency', ...

+    * ValidateBeforeAdd, which is called before an object is added to a
+      Schedule. With the default loader the object is added to the Schedule if
+      this function returns True, and is not added if it returns False.
+    * ValidateAfterAdd, which is called after an object is added to a Schedule.
+      With the default Loader the return value, if any, is not used.
