> for example, coordinator.xml
> -----
>     <input-events>
>          <data-in name="foo" dataset="bar">
>             <start-instance>${coord:latest(-365)}</start-instance>
>             <end-instance>${coord:latest(0)}</end-instance>
>          </data-in>
>     </input-events>
> -----
> there are use cases to use the same coordinator.xml for varying number of data instances (not always 365). but the parameter to coord EL function cannot be parametrized (by using job
> config), customer needs to copy coordinator.xml with different number just to change the parameter of coord:latest(), which is not optimal for maintenance.
