                                     still running. Optionl, defaults to true.
                 A trigger element has the following child elements:
                    cron: A string expression defining the scheduling timing.
                          Optional. If not specified the following elements are explored:
                       seconds:  A string expression for the secods part of a cron expression.
                       minutes:  A string expression for the secods part of a cron expression.
                       hours:    A string expression for the secods part of a cron expression.
                       days:     A string expression for the secods part of a cron expression.
                       month:    A string expression for the secods part of a cron expression.
                       weekdays: A string expression for the secods part of a cron expression.
