Can CloudFormation output an array

I have a CloudFormation template, and its Outputs part is like this:

"Outputs": {
    "QueueSubscriptions": {
        "Description": "Topics subscribed by queue",
        "Value": {
            "Fn::GetAtt" : [ "BRIDGE2ESBQUEUE", "Subscriptions" ]
        }
    }
}

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

You should be able to use the Fn::Join intrinsic function like this:

"Outputs": {
    "QueueSubscriptions": {
        "Description": "Topics subscribed by queue",
        "Value": {
            "Fn::Join" : [ ",", { "Fn::GetAtt" : [ "BRIDGE2ESBQUEUE", "Subscriptions" ] } ]
        }
    }
}
