    <description summary="virtual keyboard">
      The virtual keyboard provides an application with requests which emulate
      the behaviour of a physical keyboard.

      This interface can be used by clients on its own to provide raw input
      events, or it can accompany the input method protocol.

    <request name="keymap">
      <description summary="keyboard mapping">
        Provide a file descriptor to the compositor which can be
        memory-mapped to provide a keyboard mapping description.
