Hi All

I would like to build a configuration file for my application in XML.
The Configuration files includes also optional sections
i.e.  there might be properties that are not required to be 
defined by the user. 

If I use BOOST serialization to load this file, the XML format seems to me
that forces every field of the XML field to be REQUIRED.
 

Do you know if with Boost serialization for XML there is some mechanism
allowing or handling optional Xml field?

Kind Regards
Manu
