Specifies the type of state:

- A Normal object state.

- The Initial state at the time of creation.

- A Final object state.

- A Deep History object state represents the most recent active configuration of the composite state that directly contains this pseudostate; that is, the state configuration that was active when the composite state was last exited.

- A Shallow History object state represents the most recent active substate of its containing state.

- An Activity, meaning it executes a series of non-atomic steps of a certain duration.

- An Action, representing the execution of an atomic action. The outgoing transition is triggered as soon as the action has completed its execution.

- A Fork, where several activities are launched simultaneously.

- A Join, where several activities merge into one.

- A Choice, allowing selection between several possible transitions.

- A Junction of several transitions from orthogonal regions.

- A Synchronization of several concurrent regions of a states machine.

- An Object flow that is in the process of circulation. This kind of state terminates when the object flow reaches its destination. Example: an order in the 'Delivery in progress' state.In this case, it is possible to specify the corresponding class and its state. These are then displayed instead of the state name.
