Where is the initial X-based ttsession started?

The first call to tt_open automatically starts ttsession if no ttsession is running. However, the /usr/dt/bin/Xsession file contains an entry such as the following, which will start a ttsession at login time automatically if you are using /usr/dt/bin/dtlogin:

# Start ttsession here.
  dtstart_ttsession="$DT_BINPATH/ttsession"
