+    <description summary="input method context">
+      Corresponds to a text model on input method side. An input method context
+      is created on text mode activation on the input method side. It allows to
+      receive information about the text model 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+      which are based on an outdated state (for example after a reset).

+    <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

+      commit_state request and are used by the input method to indicate
