   <interface name="zwp_input_method_context_v1" version="1">
     <description summary="input method context">
       Corresponds to a text input on the input method side. An input method context
       is created on text input activation on the input method side. It allows to
       receive information about the text input from the application via events.
       Input method contexts do not keep state after deactivation and should be
       destroyed after deactivation is handled.

       Text is generally UTF-8 encoded, indices and lengths are in bytes.

       Serials are used to synchronize the state between the text input and
       an input method. New serials are sent by the text input in the
       commit_state request and are used by the input method to indicate
       the known text input state in events like preedit_string, commit_string,
       and keysym. The text input can then ignore events from the input method
       which are based on an outdated state (for example after a reset).

       Warning! The protocol described in this file is experimental and
       backward incompatible changes may be made. Backward compatible changes
       may be added together with the corresponding interface version bump.
       Backward incompatible changes are done by bumping the version number in
       the protocol and interface names and resetting the interface version.
       Once the protocol is to be declared stable, the 'z' prefix and the
       version number in the protocol and interface names are removed and the
       interface version number is reset.
