Hi Timothee, Daniel, All,

I was thinking of along same lines as Timothee, when writing my earlier
post today. But I now hope to understand Daniel's point of not including
this into libxml:

While processing, especially updating, your mixed XML/binary data you
hold them in an application dependant form, matching your processing
requirements. For example multiple files in a subdirectory or multiple
forks of a file if supported by your filesystem.

When freezing or transmitting the data, you convert to the ZIP file format,
Daniel adopted to support.

Regards,
Peter
