如何使用duoshuo的PHP客户端库定义嵌套在UDT中的Cassandra CollectionMap？

I have a CollectionSet<UDT> where UDT contains a CollectionMap<int,boolean>. I have not been able to find any documentation or example of how to define this when creating a new Cassandra\Type\CollectionSet for inserting into the table. There is a great example with a CollectionList (found here) which is like this:

// CollectionSet<UDT>, where UDT contains: Int, Text, Boolean, 
// CollectionList<Text>, CollectionList<UDT>

new Cassandra\Type\CollectionSet([
    [
        'id' => 1,
        'name' => 'string',
        'active' => true,
        'friends' => ['string1', 'string2', 'string3'],
        'drinks' => [['qty' => 5, 'brand' => 'Pepsi'], ['qty' => 3, 'brand' => 'Coke']]
    ],[
        'id' => 2,
        'name' => 'string',
        'active' => false,
        'friends' => ['string4', 'string5', 'string6'],
        'drinks' => []
    ]
], [
    [
    'type' => Cassandra\Type\Base::UDT,
    'definition' => [
        'id' => Cassandra\Type\Base::INT,
        'name' => Cassandra\Type\Base::VARCHAR,
        'active' => Cassandra\Type\Base::BOOLEAN,
        'friends' => [
            'type' => Cassandra\Type\Base::COLLECTION_LIST,
            'value' => Cassandra\Type\Base::VARCHAR
        ],
        'drinks' => [
            'type' => Cassandra\Type\Base::COLLECTION_LIST,
            'value' => [
                'type' => Cassandra\Type\Base::UDT,
                'typeMap' => [
                    'qty' => Cassandra\Type\Base::INT,
                    'brand' => Cassandra\Type\Base::VARCHAR
                ]
            ]
        ]
    ]
]
]);

I've tried using the above example with several variations to accommodate the CollectionMap but nothing is working. My last attempt was this

new Cassandra\Type\CollectionSet($udt_array, [[
                'type'=>Cassandra\Type\Base::UDT,
                'definition' => [
                    'map_name' => [
                        'type' => Cassandra\Type\Base::COLLECTION_MAP,
                        'value' => [
                            Cassandra\Type\Base::INT,
                            Cassandra\Type\Base::BOOLEAN
                        ]
                    ]
                ]
            ]])

which gives the error Caught exception: Since v0.7, collection types should have \"definition\" directive. I've also tried using 'definition' instead of 'value'. I'm running out of ideas, any help would be greatly appreciated.

Use "definition" instead of "value". I tried this before but apparently I was doing something else wrong because this worked.

new Cassandra\Type\CollectionSet($udt_array, [[
                'type'=>Cassandra\Type\Base::UDT,
                'definition' => [
                    'map_name' => [
                        'type' => Cassandra\Type\Base::COLLECTION_MAP,
                        'definition' => [
                            Cassandra\Type\Base::INT,
                            Cassandra\Type\Base::BOOLEAN
                        ]
                    ]
                ]
            ]])
