-  <interface name="gtk_text_input" version="1">
-    <description summary="text input">
-      The gtk_text_input interface represents text input and input methods
-      associated with a seat. It provides enter/leave events to follow the
-      text input focus for a seat.
-
-      Requests are used to enable/disable the text-input object and set
-      state information like surrounding and selected text or the content type.
-      The information about the entered text is sent to the text-input object
-      via the pre-edit and commit_string events. Using this interface removes
-      the need for applications to directly process hardware key events and
-      compose text out of them.
-
-      Text is valid UTF-8 encoded, indices and lengths are in bytes. Indices
-      have to always point to the first byte of an UTF-8 encoded code point.
-      Lengths are not allowed to contain just a part of an UTF-8 encoded code
-      point.
-
-      Focus moving throughout surfaces will result in the emission of
-      gtk_text_input.enter and gtk_text_input.leave events. The focused
-      surface must perform gtk_text_input.enable and
-      gtk_text_input.disable requests as the keyboard focus moves across
-      editable and non-editable elements of the UI. Those two requests are not
-      expected to be paired with each other, the compositor must be able to
-      handle consecutive series of the same request.
-
-      State is sent by the state requests (set_surrounding_text,
-      set_content_type and set_cursor_rectangle) and a commit request.
-      After an enter event or disable request all state information is
-      invalidated and needs to be resent by the client.
-
-      This protocol defines requests and events necessary for regular clients
-      to communicate with an input method. The gtk_input_method protocol
-      defines the interfaces necessary to implement standalone input methods.
-      If a compositor implements both interfaces, it will be the arbiter of the
-      communication between both.
-
-      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.
