            [TD] => xx
            [F] => 1
            [FE] => xxxx-xx-x
            [RR] => 1-9
            [RSR] => x x
            [MNT] => 7788
            [IT1] => 0.822 ARRO ARTE WIN  $3694 Kg
            [CAF] => Array
                (
                    [DA] => Array
                        (
                            [RE] => xxxxxxxx-x
                            [RS] => xxxxx xx xxx xxx
                            [TD] => 39
                            [RNG] => Array
                                (
                                    [D] => 1
                                    [H] => 1000
                                )

                            [FA] => xxxx-xx-xx
                            [RSAPK] => Array
                                (
                                    [M] => 3kVbG7nlR9z+xxxxx/5PctrJLCxa+xxxxxx8QIaGeu8to0w==
                                    [E] => Aw==
                                )

                            [IDK] => 100
                        )

                    [FRMA] => Array
                        (
                            [!algoritmo] => SHA1withRSA
                            [!] => VJc7/YNOBQBT7Wd+xxxxxxxxx/fn76l0n3KFViVxQ4pm/cR/y72xzqYxxxxxxx==
                        )

                    [!version] => 1.0
                )

            [TSTED] => xxxx-xx-13T01:22:10
        )

    [FRMT] => Array
        (
            [!algoritmo] => SHA1withRSA
            [!] => xxxxxxxx/MC7A7PRANIfrK630x8NveIe43455plrunRCx5g==
        )

    [!version] => 1.0
)

la idea es dejar lo como este
