+This example shows how to save/load the object model to/from a custom
+format using the Boost serialization library as an example. You will
+need the Boost serialization library[1] installed in order to build
+and run this example.
+
+[1] http://www.boost.org
+
+The example consists of the following files:
+
+library.xsd
+  XML Schema which describes a library of books.
+
+library.xml
+  Sample XML instance document.
+
+boost-archive-extraction.hxx
+boost-archive-insertion.hxx
+  Boost archive insertion and extraction operators for fundamental
+  types. You will need to provide a similar set of operators for
+  your own stream types.
+
+library-prologue.hxx
+  Contains a number of #include directives that are inserted into
+  the generated code by the XSD compiler. The included files are:
+  boost/archive/text_oarchive.hpp, boost/archive/text_oarchive.hpp,
+  boost-archive-insertion.hxx, and boost-archive-insertion.hxx.
+
+library.hxx
+library.cxx
+  C++ types that represent the given vocabulary as well as Boost
+  archive insertion and extraction operations. These are generated
+  by the XSD compiler from library.xsd. The --hxx-prologue-file
+  option is used to insert the contents of the library-prologue.hxx
+  file into the generated header file. The --generate-insertion and
+  --generate-extraction options are used to generate the insertion
+  and extraction operations for text_oarchive and text_iarchive
+  types.
+
+driver.cxx
+  Driver for the example. It first calls one of the parsing functions
+  that constructs the object model from the input XML file. It then
+  saves the object model to text_oarchive and loads it back from
+  text_iarchive. Additionally, it prints the resulting text
+  representation as well as the content of the object model before
+  saving it to text_oarchive and after loading it from text_iarchive.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver library.xml
