Nested Element Summary
	`Breaks` This optional module can be used to define different types of breaks that should be assigned by the solver during the scheduled working time of the employees.
	`Demands` Contains the required staffing levels, either as a list of tasks or time-based (timeslot or shift).
	`Employees` Contains information about available employees and their contracts.
	`General` Contains general information about the scheduling horizon and the problem instance.
	`Shifts` Contains the definitions of all feasible shift types that can be used in the solution.
	`Tasks` Contains the optional definitions of all possible task types that can be used in the solution.

Attribute Summary
`ID`	`ID` An ID used to identify the instance.
