Class.query can only work if you are using a scoped session, which isn't appropriate for many kinds of application. Session.query(Class) is completely general and will work anywhere, and is therefore more appropriate for use in the documentation. As the post in the TurboGears thread points out, you can easily add Class.query using the query_property method of the scoped session.
