Detailed Description

Note to all triers: It's not guaranteed that the specified component will be selected (if the user denies to perform dependency resolution, all changes will be reverted).

Consequently, it's essential to check the selected values after calling any trier.

Note to ctor & insert_element: Please note that the ctor collects data for scenario elements from "multiplayer" nodes, while insert_element from "scenario" nodes.
