From Sam Hurst:
Be more explicit in the "Channel Management" section that the client is not obligated to join the multicast channel once it receives an MC_SESSION_JOIN frame. If it chooses not to, it has the option to send an MC_SESSION_STATE_CHANGE frame with the "declined join" reason, but that isn't actually mentioned in the session management section.
