You are right that this OOo feature is not contained in ODF 1.1, but we 
may of course add it as part of the package definition for ODF 1.2.

A zip within zip is used because this allows extracting the versioned 
document without repackaging it. Repackaging the document would require 
to rebuild a manifest.xml.
