+Uuid
+====
+
+.. versionadded:: 2.5
+    The Uuid constraint was introduced in Symfony 2.5.
+
+Validates that a value is a valid `Universally unique identifier (UUID)`_ per `RFC 4122`_.
+By default, this will validate the format according to the RFC's guidelines, but this can
+be relaxed to accept non-standard UUIDs that other systems (like PostgreSQL) accept.
+UUID versions can also be restricted using a whitelist.

+Options
+-------
+
+message
+~~~~~~~
+
+**type**: ``string`` **default**: ``This is not a valid UUID.``
+
+This message is shown if the string is not a valid UUID.
+
+strict
+~~~~~~
+
+**type**: ``boolean`` **default**: ``true``
+
+If this option is set to ``true`` the constraint will check if the UUID is formatted per the
+RFC's input format rules: ``216fff40-98d9-11e3-a5e2-0800200c9a66``. Setting this to ``false``
+will allow alternate input formats like:
+
+* ``216f-ff40-98d9-11e3-a5e2-0800-200c-9a66``
+* ``{216fff40-98d9-11e3-a5e2-0800200c9a66}``
+* ``216fff4098d911e3a5e20800200c9a66``
+
+versions
+~~~~~~~~
+
+**type**: ``int[]`` **default**: ``[1,2,3,4,5]``
+
+This option can be used to only allow specific `UUID versions`_.  Valid versions are 1 - 5.
+The following PHP constants can also be used:
+
+* ``Uuid::V1_MAC``
+* ``Uuid::V2_DCE``
+* ``Uuid::V3_MD5``
+* ``Uuid::V4_RANDOM``
+* ``Uuid::V5_SHA1``
+
+All five versions are allowed by default.
