>1.2. What is this spec?</A
></H2
><P
>This spec defines interactions between window managers, applications,
and the utilities that form part of a desktop environment. It builds
on the ICCCM [2], which defines WM (window manager) interactions at a
lower level. The ICCCM does not provide ways to implement many
features that modern desktop users expect. The GNOME and KDE desktop
projects originally developed their own extensions to the ICCCM to
support these features; this spec replaces those custom extensions
with a standardized set of ICCCM additions that any desktop
environment can adopt.

></H2
><P
>The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be
interpreted as described in RFC 2119.
</P
><P
>The key words "Window Manager" refer to a window manager which is adopting this
specification. "Pager" refers to desktop utility applications, including
pagers and taskbars. "Application" refers to other clients. "Clients" refers
to Pagers + Applications ie. all X clients, except for the Window Manager.

>Window Managers and Clients which aim to fulfil this specification MUST adhere
to the ICCCM on which this specification builds. If this specification
explicitly modifies the ICCCM Window Managers and Clients MUST fulfil these
modifications.
