+This example shows how to use type customization to parse and serialize
+mixed content. The example achieves this by customizing the type with
+the mixed content model to include a DOM document that stores the data
+as a raw XML representation. The customized type also provides its own
+parsing constructor and serialization operator where the mixed content
+is extracted from and inserted back to DOM, respectively. The use of
+DOM for mixed content storage is one of the options. You may find other
+data structures (e.g., a string) more suitable depending on your situation.
+
+For more information on the C++/Tree mapping customization see the C++/Tree
+Mapping Customization Guide[1].

+
+The example consists of the following files:
+
+people.xsd
+ XML Schema definition for a simple person record vocabulary. Each
+ record includes the bio element which represents arbitrary XHTML
+ fragments as mixed content.
+
+people.xml
+ Sample XML instance document.
+
+people.hxx
+people.ixx
+people.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 people.xsd
+ with the --custom-type option in order to customize the bio type.
+
+people-custom.hxx
+ Header file which defines our own bio class by inheriting from the
+ generated bio_base. It is included at the end of people.hxx using
+ the --hxx-epilogue option.
+
+people-custom.cxx
+ Source file which contains the implementation of our bio 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 data to STDERR, including the bio information converted to text.
+ Finally, the driver serializes the object model back to XML.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver people.xml
