        // what follows now has weird consequences:
        // * the material is added to the ScoringParameterSet of the default subpopulation
        // * if someone uses the following in the config.xml:
        //      < ... planCalcScore ... >
        //            <... modeParams ... >
        //                   < ... mode ... abc ... />
        //    then abc will be _added_ to the modes info below (same for activities)
        //  * if, however, someone uses in the config.xml:
        //      < ... planCalcScore ... >
        //            < ... scoringParameters ... >
        //                  <... modeParams ... >
        //                        < ... mode ... abc ... />
        //     (= fully hierarchical format), then the default modes will be removed before adding mode abc.  The reason for this is that the second
        //     syntax clears the scoring params for the default subpopulation.

        //  Unfortunately, it continues:
        //  * Normally, we need a "clear defaults with first configured entry" (see PlansCalcRouteConfigGroup).  Otherwise, we fail the write-read
        //  test: Assume we end up with a config that has _less_ material than the defaults.  Then we write this to file, and read it back in.  If
        //  the defaults are not cleared, they would now be fully there.
        //  * The reason why this works here is that all the material is written out with the fully hierarchical format.  I.e. it actually clears the
        //  defaults when being read it.

        // I am not sure if it can stay the way it is right now; took me several hours to understand it (and fix a problem we had not by
        // trial-and-error but by understanding the root cause).  Considerations:
        // * Easiest would be to not have defaults.  However, defaults are helpful in particular to avoid that everybody uses different parameters.
        // * We could also have the "manual addition triggers clearing" logic.  In PlansCalcRouteConfigGroup I now have this with a warning, which
        // can be switched off with a switch.  I find this a good solution; I am, however, not 100% certain that it is robust since that switch is a
        // "state" while "clearing the defaults" is an action, and I am not sure if they can be mapped into each other in all cases.
        // * We could, together with the previous point, disallow the not fully hierarchical format.
