What happened to the "XDM-AUTHORIZATION-2" authentification scheme ?

[Roland Mainz]

Hi!

----

While reading http://www.x.org/IPV6_Review.html I saw that
XDM-AUTHORIZATION-1 was superset with XDM-AUTHORIZATION-2 to provide
IPv6 support and stronger (AES-based) authentification...
... but when I search for that in the xc/ source tree the only
references to XDM-AUTHORIZATION-2 are:
-- snip --
% fgrep -r XDM-AUTHORIZATION-2 xc
xc/programs/Xserver/Xserver._man:XDM-AUTHORIZATION-2, SUN-DES-1, and
MIT-KERBEROS-5.  See the 
xc/programs/Xserver/Xserver.man:XDM-AUTHORIZATION-2, SUN-DES-1, and
MIT-KERBEROS-5.  See the 
xc/programs/Xserver/Xserver.1x.html:XDM-AUTHORIZATION-1,
XDM-AUTHORIZATION-2, SUN-DES-1, and MIT-KERBEROS-5.  See the
-- snip --
What happened to the XDM-AUTHORIZATION-2 authentification scheme ? Was
it dropped later, just forgotten or something else ?
