The definition of a session data container is in the docs. The keys of a session data container, each of which represents a particular session, are (in the current implementation) derived from the session token, which comes out of the request in a cookie or a formvar, and is a string.
PS: SessionDataContainers are the things that sit on web pages and in cookies identifying users right? In which case, I see no reason (or possibility) for them not to be strings...
