+Symfony Translation Contracts
+=============================
+
+A set of abstractions extracted out of the Symfony components.
+
+Can be used to build on semantics that the Symfony components proved useful - and
+that already have battle tested implementations.
+
+See https://github.com/symfony/contracts/blob/main/README.md for more information.

+     *
+     * Given a message with different plural translations separated by a
+     * pipe (|), this method returns the correct portion of the message based
+     * on the given number, locale and the pluralization rules in the message
+     * itself.
+     *
+     * The message supports two different types of pluralization rules:
+     *
+     * interval: {0} There are no apples|{1} There is one apple|]1,Inf] There are %count% apples
+     * indexed:  There is one apple|There are %count% apples

+     * The indexed solution can also contain labels (e.g. one: There is one apple).
+     * This is purely for making the translations more clear - it does not
+     * affect the functionality.
+     *
+     * The two methods can also be mixed:
+     *     {0} There are no apples|one: There is one apple|more: There are %count% apples
+     *
+     * An interval can represent a finite set of numbers:
+     *  {1,2,3,4}
+     *
+     * An interval can represent numbers between two numbers:
+     *  [1, +Inf]

+     *
+     * The left delimiter can be [ (inclusive) or ] (exclusive).

+-----
+
+ * added relative file path template to the file dumpers
+ * added optional backup to the file dumpers
+ * changed IcuResFileDumper to extend FileDumper
+
+2.3.0
+-----
+
+ * added classes to make operations on catalogues (like making a diff or a merge on 2 catalogues)
+ * added Translator::getFallbackLocales()
+ * deprecated Translator::setFallbackLocale() in favor of the new Translator::setFallbackLocales() method
+
+2.2.0
+-----
+
+ * QtTranslationsLoader class renamed to QtFileLoader. QtTranslationsLoader is deprecated and will be removed in 2.3.
+ * [BC BREAK] uniformized the exception thrown by the load() method when an error occurs. The load() method now
+   throws Symfony\Component\Translation\Exception\NotFoundResourceException when a resource cannot be found
+   and Symfony\Component\Translation\Exception\InvalidResourceException when a resource is invalid.
+ * changed the exception class thrown by some load() methods from \RuntimeException to \InvalidArgumentException
+   (IcuDatFileLoader, IcuResFileLoader and QtFileLoader)
+
+2.1.0
+-----
+
+ * added support for more than one fallback locale
+ * added support for extracting translation messages from templates (Twig and PHP)
+ * added dumpers for translation catalogs
+ * added support for QT, gettext, and ResourceBundles

+Translation Component
+=====================
+
+The Translation component provides tools to internationalize your application.
+
+Getting Started
+---------------
+
+```
+$ composer require symfony/translation
+```
+
+```php
+use Symfony\Component\Translation\Translator;
+use Symfony\Component\Translation\Loader\ArrayLoader;
+
+$translator = new Translator('fr_FR');
+$translator->addLoader('array', new ArrayLoader());
+$translator->addResource('array', [
+    'Hello World!' => 'Bonjour !',
+], 'fr_FR');
+
+echo $translator->trans('Hello World!'); // outputs « Bonjour ! »
+```
+

+
+    <div class="bodytext">
+     <p>
+      This schema defines attributes and an attribute group suitable
+      for use by schemas wishing to allow <code>xml:base</code>,
+      <code>xml:lang</code>, <code>xml:space</code> or
+      <code>xml:id</code> attributes on elements they define.
+     </p>
+
+     <p>
+      To enable this, such a schema must import this schema for
+      the XML namespace, e.g. as follows:
+     </p>
+     <pre>
+          &lt;schema.. .>
+          .. .
+           &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                      schemaLocation="http://www.w3.org/2001/xml.xsd"/>
+     </pre>
+     <p>
+      or
+     </p>
+     <pre>
+
+           &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                      schemaLocation="http://www.w3.org/2009/01/xml.xsd"/>
+     </pre>
+     <p>
+      Subsequently, qualified reference to any of the attributes or the
+      group defined below will have the desired effect, e.g.
+     </p>
+     <pre>
+          &lt;type.. .>
+          .. .
+           &lt;attributeGroup ref="xml:specialAttrs"/>
+     </pre>
+     <p>
+      will define a type which will schema-validate an instance element
+      with any of those attributes.

+      The schema document at that URI may however change in the future,
