Yes, the Bitrix ValidationService allows you to validate service and business logic objects, configure custom validators, and register custom rules to collect errors within an ErrorCollection.

Yes, attribute-based validation in Bitrix requires PHP 8 to utilize native attributes like #[NotEmpty] and #[Email] for rule definitions and to run the Bitrix ValidationService effectively.
