FSMCFRFF — In Figure 7.9 and Figure 7.14, the sequence diagram does not show some timing information

In Figure 7.9 and Figure 7.14, the sequence diagram does not show:

• the timing when RTObject calls update_status
• the timing when Tool calls remove_service
• the timing when ComponentObserver is destroyed.

Add timing information to Figure 7.9 and Figure 7.14

To show timing information clearer, opt fragments are added to sequence diagrams in Figure 7.9 and Figure 7.14.
