/**
 * Allows to group multiple rules for validation. It's helpful when `skipOnEmpty`, `skipOnError` or `when` options are
 * the same for every rule in the set.
 *
 * For example, with the same `when` closure, without using composite it's specified explicitly for every rule:
 *
 * ```php
 * $when = static function ($value, ValidationContext $context): bool {
 *     return $context->getDataSet()->getAttributeValue('country') === Country::USA;
 * };
 * $rules = [
 *     new Required(when: $when),
 *     new HasLength(min: 1, max: 50, skipOnEmpty: true, when: $when),
 * ];
 * ```
 *
 * When using composite, specifying it only once will be enough:
 *
 * ```php
 * $rule = new Composite([
 *     new Required(),
 *     new HasLength(min: 1, max: 50, skipOnEmpty: true),
 *     when: static function ($value, ValidationContext $context): bool {
 *         return $context->getDataSet()->getAttributeValue('country') === Country::USA;
 *     },
 * ]);
 * ```
 *
 * Another use case is reusing this rule group across different places. It's possible by creating own extended class and
 * setting the properties in the constructor:
 *
 * ```php
 * class MyComposite extends Composite
 * {
 *     public function __construct()
 *     {
 *         $this->rules = [
 *             new Required(),
 *             new HasLength(min: 1, max: 50, skipOnEmpty: true),
 *         ];
 *         $this->when = static function ($value, ValidationContext $context): bool {
 *             return $context->getDataSet()->getAttributeValue('country') === Country::USA;
 *         };
 *     }
 * };
 * ```
 *
 * @see CompositeHandler Corresponding handler performing the actual validation.
