Dynamic session variables
-------------------------
When you create a permission, or an access control rule, the permission rule itself needs access to some variables
that are derived from the request itself. Let's refer to these as *session variables*.
Permission rules can also refer to *session variables*. Session variables are key-value pairs returned from the authentication service for each request.
For example: If a user makes a request, the session token maps to a ``user-id``. This ``user-id`` can be used in
a permission to show that inserts into a table are only allowed if the ``user_id`` column has a value equal to that
