The principal is A in the statement "A has permission to do B to C where D applies."
In an access control policy statement, you can set the principal to all authenticated AWS users through the {@link Principal#AllUsers} member. Thisis useful when you don't want to restrict access based on the identity of the requester, but instead on other identifying characteristics such as the requester's IP address.
The implementation SimplePrincipal just contains the Id property. More complex Principal objects may contain additional information that are meaningful to the View layer but are generally transparent to the rest of CAS.
