+This example shows how to customize the XML Schema built-in types by mapping
+xsd:date built-in type to the date class from the Boost date_time library.
+You will need the Boost date_time library[1] installed in order to build
+and run this example. For more information on the C++/Tree mapping
+customization see the C++/Tree Mapping Customization Guide[2].
+
+[1] http://www.boost.org
+[2] http://wiki.codesynthesis.com/Tree/Customization_guide
+
+The example consists of the following files:
+
+calendar.xsd
+  XML Schema definition for a simple calendar format.
+
+calendar.xml
+  Sample XML instance document.
+
+xml-schema.hxx
+  C++ types for XML Schema built-in types. This header file is generated
+  by XSD using the --generate-xml-schema option. The --custom-type option
+  is also used to customize the xsd:date type.
+
+calendar.hxx
+calendar.ixx
+calendar.cxx
+  C++ types that represent the given 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 calendar.xsd with the
+  --extern-xml-schema option in order to include xml-schema.hxx.
+
+xml-schema-custom.hxx
+  Header file which defines our own xml_schema::date class. It is
+  included at the end of xml-schema.hxx using the --hxx-epilogue
+  option.
+
+xml-schema-custom.cxx
+  Source file which contains the implementation of our xml_schema:date
+  class.
+
+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 calendar events to STDERR.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver calendar.xml
