+This example shows how to use the C++/Tree mapping to parse XML documents
+into a tree-like in-memory object model, modify this object model, and
+finally serialize it back to XML.
+
+The example consists of the following files:
+
+library.xsd
+  XML Schema which describes a library of books.
+
+library.xml
+  Sample XML instance document.
+
+library.hxx
+library.ixx
+library.cxx
+  C++ types that represent the given vocabulary, a set of parsing
+  functions that convert XML documents to a tree-like in-memory object
+  model, and a set of serialization functions that convert the object
+  model back to XML. These are generated by XSD from library.xsd.
+
+driver.cxx
+  Driver for the example. It first calls one of the parsing functions
+  that constructs the object model from the input file. It then prints
+  the content of the object model to STDERR. Finally, the driver modifies
+  the object model and serializes it back to XML.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver library.xml
+
+This example also shows how to to use the ID/IDREF cross-referencing
+mechanism and the xsd:enumeration to C++ enum mapping.
