+Compound
+========
+
+To the contrary to the other constraints, this constraint cannot be used on its own.
+Instead, it allows you to create your own set of reusable constraints, representing
+rules to use consistently across your application, by extending the constraint.
+
+.. versionadded:: 5.1
+
+    The ``Compound`` constraint was introduced in Symfony 5.1.
+
+==========  ===================================================================
+Applies to  :ref:`class <validation-class-target>` or :ref:`property or method <validation-property-target>`
+Options     - `groups`_
+            - `payload`_
+Class       :class:`Symfony\\Component\\Validator\\Constraints\\Compound`
+Validator   :class:`Symfony\\Component\\Validator\\Constraints\\CompoundValidator`
+==========  ===================================================================
+
+Basic Usage
+-----------
+
+Suppose that you have different places where a user password must be validated,
+you can create your own named set or requirements to be reused consistently everywhere::
+
+    // src/Validator/Constraints/PasswordRequirements.php
+    namespace App\Validator\Constraints;
+
+    use Symfony\Component\Validator\Compound;
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    /**
+     * @Annotation
+     */
+    class PasswordRequirements extends Compound
+    {
+        protected function getConstraints(array $options): array
+        {
+            return [
+                new Assert\NotBlank(),
+                new Assert\Type('string'),
+                new Assert\Length(['min' => 12]),
+                new Assert\NotCompromisedPassword(),
+            ];
+        }
+    }
+
+You can now use it anywhere you need it:
+
+.. configuration-block::
+
+    .. code-block:: php-annotations
+
+        // src/User/RegisterUser.php
+        namespace App\User;

+             * @AcmeAssert\PasswordRequirements()
+             */
