I saw that the constraint voucher follows the same approach.

Maybe related to this, would it be better to augment the voucher than as requested by Reshad or the voucher-request as we currently do it. I also had a look into the constraint voucher as there are also enhancements defined. So I guess I should go with the augmented voucher?

I meanwhile changed it to vcr. If it has no relevance outside the module, it should not be a problem
