 * A security context is a set of security attributes

 * externally represented as variable-length strings
 * that can be interpreted by a user or application
 * with an understanding of the security policy. 
 * Internally, the security server uses a simple
 * structure.  This structure is private to the
 * security server and can be changed without affecting
 * clients of the security server.
