The concept Key is a unique identifier for something in some sort of table. In general, they can be only created by the table and are returned when a appropriate new_foo() method is called on the table. There are two classes of values for a Key, valid and invalid. The latter cannot refer to something in a table. Use the method is_valid() to differentiate.
