Why do we always need a lifecycle state named "initial" in a lifecycle definition?
When defining a lifecycle via a SCXML, you can specify the permissions that are allowed at each state in the lifecycle. The first state in a lifecycle needs to always be initial as ES needs to maintain this virtual state to execute the initial permission logic when the initial state change occurs. When an asset is created, ES automatically promotes the asset from the initial state to the created state and assigns the respective permissions. Note that the initial state is a virtual state and that the created state is the first logical state.

Why is there a state named "initial" in a lifecycle?
When defining an asset via an RXT, you can specify the permissions that are allowed at each state in the lifecycle. Furthermore, when an asset is created, ES automatically promotes it from the initial state to the created state and assigns the respective permissions. The initial state is added in a lifecycle, so that ES can define the permissions that need to be assigned when the asset is in the created state, which is the first logical state.
