// Format provides a CEL library exposing common named Kubernetes string
// validations. Can be used in CRD ValidationRules messageExpression.
//
//  Example:
//
//    rule:              format.dns1123label.validate(object.metadata.name).hasValue()
//    messageExpression: format.dns1123label.validate(object.metadata.name).value().join("\n")
//
// format.named(name: string) -> ?Format
//
