* The way structure are organised in a "derived" manner.
* Each of the state structure must directly "castable" into the descriptor
* that the state variable relies upon.
*
* For instance, if a stream_input descriptor is created, the state structure
* stream_input_state needs to be created as follow:
*
* struct stream_input_state {
* struct stream_input_desc ...
* ...
* This way it's possible to get directly from the AEM command the descriptor
* and the state without having to create a mechanism for this.
