 You might be better off watching
 https://svn.boost.org/trac/boost/ticket/8088


 In the end I converted my project to use boost::property_tree.  Older
 versions of the application, written to use boost::serialization, couldn't
 load the boost::property_tree XML, but since they did't have future
 compatibility anyway, it wasn't much of a loss.  However applications
 written to use boost::property_tree can easily load boost::serialization
 XML.  And once you've made the jump, boost::property_tree provides better
 support for skipping extra data, and handling missing data.  All-in-all it
 was a fairly painless conversion.

 There are caveats:

 * If you need object tracking then boost::property_tree is of no use to
 you.  But as I noted above I couldn't work out a way to modify
 boost::serialization to support future compatibility ''and'' object
 tracking (not fully at any rate).  Perhaps others are more insightful.

 * The two libraries almost certainly have different memory/performance
 characteristics but again that didn't affect my project.

 * If you need UTF-8 support you'll need to imbue your input/output stream
 before calling boost::property_tree::read_xml/write_xml.  (UTF-8 support
 isn't out-of-the-box.)

 I hope that's of some use to you.
