+This example shows how to handle the xsi:type attributes when it is used
+on root elements. For general coverage of XML Schema polymorphism handling
+in the C++/Parser mapping see the polymorphism example.
+
+The example consists of the following files:
+
+supermen.xsd
+ XML Schema which describes the "supermen" instance documents.
+
+person.xml
+superman.xml
+batman.xml
+ Sample XML instance documents.
+
+supermen-pskel.hxx
+supermen-pskel.cxx
+ Parser skeletons generated by the XSD compiler from supermen.xsd.
+ Note the use of the --generate-polymorphic command line option.
+
+supermen-pimpl.hxx
+supermen-pimpl.cxx
+ Parser implementations that print the XML data to STDOUT.
+
+driver.cxx
+ Driver for the example. It implements a custom document parser
+ that determines which XML Schema type is being parsed and uses
+ the corresponding parser implementation. The driver first
+ constructs a parser instance from all the individual parsers
+ found in supermen-pimpl.hxx. In then invokes this parser instance
+ to parse the input file.
+
+To run the example on the sample XML instance documents simply execute:
+
+$ ./driver person.xml
+$ ./driver superman.xml
+$ ./driver batman.xml
