+This example shows how to use the C++/Tree mapping together with XPath.
+In particular, it shows how to execute an XPath query on the underlying
+DOM document and then handle the result using the more convenient object
+model representation. For more information on maintaining association
+with the underlying DOM document, refer to Section 5.1, "DOM Association"
+in the C++/Tree Mapping User Manual.
+
+You will need the XQilla library[1] which provides XQuery and XPath 2
+support on top of Xerces-C++ in order to build and run this example.
+
+[1] http://xqilla.sourceforge.net
+
+The example consists of the following files:
+
+people.xsd
+  XML Schema definition for a simple person record vocabulary.
+
+people.xml
+  Sample XML instance document.
+
+people.hxx
+people.cxx
+  C++ types that represent the person record vocabulary and a set of
+  parsing functions that convert XML instance documents to a tree-like
+  in-memory object model.
+
+  These files are generated by the XSD compiler from people.xsd using
+  the following command line:
+
+  xsd cxx-tree people.xsd
+
+dom-parse.hxx
+dom-parse.cxx
+  Definition and implementation of the parse() function that parses an
+  XML document to a DOM document.
+
+driver.cxx
+  Driver for the example. It first calls the above parse() function to
+  parse the input file to a DOM document using XQilla-provided DOM
+  Implementation with support for XPath 2. It then parses the DOM
+  document to the object model. Finally, it prepares and executes
+  an XPath query on the underlying DOM document and then handles
+  the result by getting back from the returned DOM nodes to object
+  model nodes.
+
+To compile and link the example manually from the command line we can use
+the following commands (replace 'c++' with your C++ compiler name):
+
+c++ -DXSD_CXX11 -c people.cxx
+c++ -DXSD_CXX11 -c dom-parse.cxx
+c++ -DXSD_CXX11 -c driver.cxx
+c++ -o driver driver.o people.o dom-parse.o -lxqilla -lxerces-c
+
+Note that we need to define the XSD_CXX11 preprocessor macro since the
+source code includes libxsd headers directly.
+
+To run the example on the sample XML document execute:
+
+./driver people.xml
