+This example shows how to use XML Schema polymorphism features such as
+xsi:type attributes and substitution groups in the C++/Tree mapping.
+
+The example consists of the following files:
+
+supermen.xsd
+  XML Schema which describes the "supermen" instance documents.
+
+supermen.xml
+  Sample XML instance document.
+
+supermen.hxx
+supermen.cxx
+  C++ types that represent the given vocabulary, a set of parsing
+  functions that convert XML instance 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 supermen.xsd.
+  Note also that we use the --generate-polymorphic command line option
+  and that we don't need to use --polymorphic-type to explicitly mark 
+  types as polymorphic because this is automatically deduced by the
+  XSD compiler from the substitution groups used in the supermen.xsd
+  schema.
+
+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 serializes
+  the object model back to XML.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver instance.xml
