I have a single class attribute, the int persistenceVersion.

For example, if I serialize an instance of a Foo(Versioned) at version 4 and then unserialize it when the code is at version 9, the calls:: self.upgradeToVersion5() self.upgradeToVersion6() self.upgradeToVersion7() self.upgradeToVersion8() self.upgradeToVersion9() will be made.
