  40808 is the Wi-Fi alliance.  They have historically been been secretive with their RADIUS dictionaries.  No idea  why.  It's like they don't want people to use their standards...

  But I'm not willing to spend $50K to join the Wi-Fi alliance, and they're not willing to share their "secret" information with people.
