UMLR — Figure 14.5 State with Compartments does not show all the compartments that it should

Before Figure 14.6. the text says:

A State may be subdivided into multiple compartments separated from each other by a horizontal line (Figure 14.6).

Immediately after Figure 14.6, the four compartments of a state are defined.

• name
• internal Behaviors
• internal Transitions
• decomposition
  —
  However, in the Figure, the internal Behaviors and internal Transitions are in the same compartment. It appears that the line between the name compartment and the remaining compartments is required but the line between the internal Behaviors and Transition is not required.

This should be made clear.

Also, the example has the items in the state in the order that the compartments would be defined. Is this required? Can I mix them if no separate compartment is used?
