### Description My client is a first class workflow user and has created custom definition validator. (Note : I should make a talk about this one day 😉) ### Example ```yaml workflows: foobars: #... regular things definition_validators: - ClassThatImplementDefinitionValidatorInterface # cf https://github.com/symfony/symfony/blob/7.1/src/Symfony/Component/Workflow/Validator/DefinitionValidatorInterface.php ``` --- If the feature is accepted, I'll take care of it
