    2020 * <p> 
    2121 * a task instance represents the execution of a specific task within a user session. A task 
    22  * instance is always related to the task that was executed. A task instance may have children 
    23  * but only if its related task allows to have children. For example, if the represented task is 
    24  * a sequence then task instance has children and these are instances of the tasks being the 
    25  * children of the related sequence. 
    26  * </p> 
    27  * <p> 
    28  * An instance of a sequence has the same number of children as the related sequence. An instance 
    29  * of a selection has only one child which is an instance of exactly one variant contained in the 
    30  * related selection. An instance of an iteration has zero or more instances of the same task 
    31  * as children where the task is the child of the related iteration. An instance of an optional 
    32  * has zero or one child where the task related to child is the child of the optional. A task 
    33  * instance related to an event task does not have children. 
     22 * instance is always related to the task that was executed.
