  JSR-303 (Bean Validation) is a Java specification that defines a metadata
  model and API for JavaBean validation. It provides a standard way to define
  validation constraints on Java objects using annotations, enabling
  developers to enforce business rules and data integrity at the object level.
  Now standardized as Jakarta Validation, with version 3.1 released for
  Jakarta EE 11 and version 4.0 under development for Jakarta EE 12.
