Yes, I know. XML cannot be called "serialization", because of its free 
ordering of elements and attributes. In the case you change the order of 
boost's serialized elements inside a XML file, in deserialization will 
throw a stream exception. Because I've touched the serialization part of 
boost the first time this was what I wanted to know exactly.

Nevertheless i wouldn't say it's impossible. When giving access to the 
classnames in boost whenever needed, the serialization to an arbitrary 
XML scheme (at least that one I need) can be done. The deserialization 
is another thing which I haven't tried to touch yet. I guess that one 
additional method can make it possible :)

So far, I take this experiences with boost::serialization with me and go 
for another solution.

Thank you
