The major goal of the MIT 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 X11R5
distribution is explained below.
The following documents are MIT X Consortium standards:
X Window System Protocol, X Version 11, Release 5,
Robert W. Scheifler
Xlib —C Language X Interface, X Version 11, Release 5,
James Gettys, Robert W. Scheifler, Ron Newman
X Toolkit Intrinsics —C Language Interface, X Version
11, Release 5 Joel McCormack, Paul Asente, Ralph R. Swick
Bitmap Distribution Format, Version 2.1, X Version 11,
Release 5 Inter-Client Communication Conventions Manual, Version
1.1, X Version 11, Release 5, David Rosenthal
Compound Text Encoding, Version 1.1, X Version 11,
Release 5, Robert W. Scheifler X Logical Font Description
Conventions, Version 1.4, X Version 11, Release 5, Jim Flowers
X Display Manager Control Protocol, Version 1.0, X
Version 11, Release 5, Keith Packard
X11 Nonrectangular Window Shape Extension, Version 1.0,
X Version 11, Release 5, Keith Packard
X11 Input Extension Protocol Specification, Version 1.0,
X Version 11, Release 5, George Sachs, Mark Patrick
X11 Input Extension Library Specification, X Version 11,
Release 5, Mark Patrick, George Sachs
The X Font Service Protocol, Version 1.0, X Version 11,
Release 5, Jim Fulton
The X11R5 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. At the public release of X11R5,
the only MIT X Consortium standards are the ones listed above. No
other documents, include files, or software in X11R5 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 Input Synthesis extension; the Athena Widget
Set; the Xmu library; the Xau library; CLX, the Common Lisp
interface to X; the RGB database; the fonts distributed with X11R5;
the applications distributed with X11R5; the include files
X11/XWDFile.h, X11/Xfuncproto.h, X11/Xfuncs.h,X11/Xosdefs.h, and X11/Xos.h; the bitmap files in
X11/bitmaps.
