3.3.7.3 Sending Compartment Status Information PDU

Upon receiving a notification from the text services framework that the current input method editor (IME) compartments has changed, the client MUST then send the new compartment information to the server using the Compartment Status Information PDU (section 2.2.2.10.2). This enables the server to stay in sync with the current compartment mode of the client.

Similarly, the server is also to send the compartment values to the client if it receives a notification from the server's text services framework.

Upon receiving this PDU from the client or server, the IME compartment status is set to the values passed in the PDU.
