          The WRIX (Wireless Roaming Intermediary Exchange) is comprised of the four specifications listed below.  The
          recommendation is for Service Providers to utilize all four of the specifications.   However, it is acceptable for
          different partners to utilize the specifications only as guidelines, or part of it, when creating and maintaining Wi-Fi
          Roaming partnerships.
