+This example shows how to perform stream-oriented, partially in-memory 
+XML processing using the C++/Tree mapping. With the partially in-memory 
+parsing and serialization only a part of the object model is in memory at
+any given time. With this approach we can process parts of the document
+as they become available as well as handle documents that are too large
+to fit into memory.
+
+The example consists of the following files:
+
+position.xsd
+  XML Schema which describes a simple object position vocabulary. The
+  position is represented as a potentially large series of latitude and
+  longitude measurements.
+
+position.xml
+  Sample object position document.
+
+position.hxx
+position.cxx
+  C++ types that represent the position vocabulary as well as parsing 
+  and serialization functions. These are generated by XSD from
+  position.xsd.
+
+parser.hxx
+parser.cxx
+  Stream-oriented DOM parser implementation that is built on top of the
+  Xerces-C++ SAX2 parser in the progressive parsing mode. This parser
+  allows us to parse an XML document as a series of DOM fragments.
+
+serializer.hxx
+serializer.cxx
+  Stream-oriented DOM serializer implementation that allows us to  
+  serialize an XML Document as a series of object model fragments.
+
+driver.cxx
+  Driver for the example. It first parses the input file into a series
+  of DOM fragments which are then parsed into the object model fragments.
+  The driver prints the information from the document as it becomes
+  available. The driver then creates a new XML document (out.xml) by
+  creating and serializing a series of object model fragments.
+
+To run the example simply execute:
+
+$ ./driver position.xml
+
+The serialization results are written to the out.xml file.
