No it isn't. The xml library we use automagically unzip any zipped files. When 
we save zip files we do it by explicitly writing the strings to file. We need 
to provide a proper zip algorithm.

boost provide such frameworks with its ostream library. I is quite neat, but 
of course it makes heavy use of templates. I used it in a previous version of 
TriTetMesh, but abandoned it because I could not figure out template related 
stuff. It should be quite straight forward for a C++ Guru to include for our 
xml files.
