  <interface name="text_model" version="1">
    <description summary="text model">
      A model for text input. Adds support for text input and input methods to
      applications. A text_model object is created from a text_model_factory and
      corresponds typically to a text entry in an application. Requests are used
      to activate/deactivate the model and set information like surrounding and
      selected text or the content type. The information about entered text is
      sent to the model 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.
    </description>
    <request name="set_surrounding_text">
      <description summary="sets the surrounding text">
        Sets the plain surrounding text around the input position. Cursor is the
        position within the surrounding text. Anchor is the position of the
        selection anchor within the surrounding text. If there is no selected
        text anchor is the same as cursor.

    <request name="activate">
      <description summary="request activation">
        Requests the model to be activated (typically when the text entry gets
        focus). The seat argument is a wl_seat which maintains the focus for
        this activation. The surface argument is a wl_surface assigned to the
        model and tracked for focus lost. The activated event is emitted on
        successful activation.
