ICCCM (Inter-Client Communication Conventions Manual). https://www.x.org/releases/X11R7.6/doc/xorg-docs/specs/ICCCM/icccm.html X deliberately specifies "mechanism, not policy" for how windows interact. As such, an additional specification beyond the X protocol itself was needed for client interoperation. The ICCCM specifies cut and paste buffers, window manager interaction, session management, how to manipulate shared resources and how to manage device colours. These low-level functions are generally implemented within widget toolkits or desktop environments. This isolates application programmers from working directly with the ICCCM itself, as this functionality is delegated to the implementing toolkit. The ICCCM is notorious for being ambiguous and difficult to correctly implement. Furthermore, some parts are obsolete or no longer practical to implement. Efforts to update and clarify the ICCCM for current needs have resulted in the Extended Window Manager Hints (EWMH), which has gained fairly broad acceptance and continues to be extended as the need arises. https://en.wikipedia.org/wiki/Inter-Client_Communication_Conventions_Manual ICCCM came in for some memorable if passing derision in The UNIX-Hater's Handbook. http://www.art.net/~hopkins/Don/unix-haters/x-windows/disaster.html -- Cheers, "The plural of regex is regrets."
