   <interface name="zwp_text_input_v1" version="1">
     <description summary="text input">
       An object used for text input. Adds support for text input and input
       methods to applications. A text_input object is created from a
       wl_text_input_manager and corresponds typically to a text entry in an
       application.

       Requests are used to activate/deactivate the text_input object and set
       state information like surrounding and selected text or the content type.
       The information about entered text is sent to the text_input object via
       the pre-edit and commit events. Using this interface removes the need
       for applications to directly process hardware key events and compose text
       out of them.

       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       which are based on an outdated state (for example after a reset).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.
