A.1 The X11R2 Draft

The February 25, 1988 draft that was distributed as part of X Version 11, Release 2 was clearly labeled as such, and many areas were explicitly labeled as liable to change.

As far as possible, we have tried to ensure that clients obeying the conventions in the X11R2 draft would will work.
