Can CloudFormation output an array
<p>I have a CloudFormation template, and its <code>Outputs</code> part is like this:</p>

<pre><code>"Outputs": {
    "QueueSubscriptions": {
        "Description": "Topics subscribed by queue",
        "Value": {
            "Fn::GetAtt" : [ "BRIDGE2ESBQUEUE", "Subscriptions" ]
        }
    }
}
</code></pre>

<p>The <code>Subscriptions</code> is an array. So, I get the error <code>Template format error: Every Value member must be a string</code>. Is there any way to output the <code>Subscriptions</code> array in the template? Thanks. </p>
