Stefan Bodewig resolved COMPRESS-102.

    Fix Version/s: 1.0

I misread the code, it already adds the signature.

>       Although not originally assigned a signature, the value 
>       0x08074b50 has commonly been adopted as a signature value 
>       for the data descriptor record.  Implementers should be 
>       aware that ZIP files may be encountered with or without this 
>       signature marking data descriptors and should account for
>       either case when reading ZIP files to ensure compatibility.
>       When writing ZIP files, it is recommended to include the
>       signature value marking the data descriptor record.  When
>       the signature is used, the fields currently defined for
>       the data descriptor record will immediately follow the
>       signature.
