.. include:: /reference/constraints/_payload-option.rst.inc

Those are the options, not the constructor arguments. What's new is that those options can be set through names arguments. Maybe we should show on https://symfony.com/doc/current/reference/constraints/Compound.html a custom compound constraint used as an attribute with a validation group.
