UMLR — A State can only have one Do/ behavior, but example shows more than one.

Figure 14.1 Behavior StateMachines indicates only 0..1 Entry, Do and Exit behavior for a state.

However, Figure 14.10 has an exit behavior as
exit / exit/ turn off main light; turn off secondary

It is unclear whether list of behaviors (separated by are to be executed serially or in parallel.

I suggest that both serial and parallel syntax be supplied and Figure 14.1 (and elsewhere) be modified to indicate more than one behavior is allowed.

Else (and less useful) Figure 14.10 has to be fixed
