+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 are generated by XSD from 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 Xerces-C++ 3.x.y/XQilla 2.2.x. 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.
+
+driver-2.cxx
+  Driver for Xerces-C++ 2.x.y/XQilla 2.1.x. It performs the same set
+  of actions as driver.cxx above. 
+
+To run the example on the sample XML document simply execute:
+
+$ ./driver people.xml
