AFAICT, the only part of 802.1AS-2011 that mentions when to transmit an announce message is Figure 10-15 on page 84. On the right hand side there is the state TRANSMIT_ANNOUNCE which calls the txAnnounce method. That state is only reachable if (selectedRole == MasterPort), and so it looks like we should not transmit when is slave only mode, just like in 1588.
