Unable to define multiple producer tags under producers

[rrehbein]

Error:
Unrecognized options "0, 1" under "old_sound_rabbit_mq.producers.producer"

Config snippet:

<?xml version="1.0" ?>
<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:rabbitmq="http://example.org/schema/dic/old_sound_rabbit_mq"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<rabbitmq:config>
    <rabbitmq:producers>
        <rabbitmq:producer key="cache_invalidation">
            <rabbitmq:exchange_options name="cache_invalidation" type="fanout" />
        </rabbitmq:producer>
        <rabbitmq:producer key="send_email">
            <rabbitmq:exchange_options name="send_email" type="direct" />
        </rabbitmq:producer>
    </rabbitmq:producers>
</rabbitmq:config>
</container>

A work around version

<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:rabbitmq="http://example.org/schema/dic/old_sound_rabbit_mq"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <rabbitmq:config>
        <rabbitmq:producers key="cache_invalidation">
            <rabbitmq:exchange_options name="cache_invalidation" type="fanout" />
        </rabbitmq:producers>
        <rabbitmq:producers key="send_email">
            <rabbitmq:exchange_options name="send_email" type="direct" />
        </rabbitmq:producers>
    </rabbitmq:config>
</container>

I haven't used Symfony for a while already. So if you could send a patch, that'd be awesome
