NAME
X Standards - X Consortium Standards

SYNOPSIS
The major goal of the X Consortium is to promote cooperation
within the computer industry in the creation of standard
software interfaces at all layers in the X Window System
environment. The status of various standards, and the
software in the X11R6 distribution, is explained below.

NON STANDARDS
The X11R6 distribution contains sample implementations, not
reference implementations. Although much of the code is
believed to be correct, the code should be assumed to be in
error wherever it conflicts with the specification.

The only X Consortium standards are the ones listed above.
No other documents, include files, or software in X11R6
carry special status within the X Consortium. For example,
none of the following are standards: internal interfaces of
the sample server; the MIT-SHM extension; the Athena Widget
Set; the Xmu library; the Xau library; the RGB database; the
fonts distributed with X11R6; the applications distributed
with X11R6; the include files <X11/XWDFile.h>,
<X11/Xfuncproto.h>, <X11/Xfuncs.h>, <X11/Xosdefs.h>,
<X11/Xos.h>, and <X11/Xthreads.h>; the bitmap files in
<X11/bitmaps>.

The following are works in progress within the X Consortium,
and are neither standards nor draft standards: Fresco; Low
Bandwidth X; X Keyboard Extension; Record Extension.
