 X Keyboard Extension
 --------------------
 
-The X Keyboard Extension essentially replaces the core protocol definition of
-keyboard. The extension makes possible to clearly and explicitly specify most
-aspects of keyboard behaviour on per-key basis and to more closely track the
-logical and physical state of the keyboard. It also includes a number of
-keyboard controls designed to make keyboards more accessible to people with
-physical impairments.

-There are five types of components in the server database corresponing to five
-xkb symbolic names: symbols, geometry, keycodes, compat and types which
