+This example shows how to reuse implementations of base parsers
+in derived parsers using the mixin C++ idiom.
+
+The example consists of the following files:
+
+schema.xsd
+ XML Schema which defined two data types: base and
+ derived.
+
+instance.xml
+ Sample XML instance document.
+
+types.hxx
+ C++ classes that correspond to the base and derived
+ types in schema.xsd.
+
+schema.map
+ Type map. It maps XML Schema types defined in schema.xsd
+ to C++ types defined in types.hxx.
+
+schema-pskel.hxx
+schema-pskel.cxx
+ Parser skeletons generated by XSD from schema.xsd and
+ schema.map.
+
+driver.cxx
+ Parser implementations and a driver for the example. It
+ shows how to mix the implementation of the base parser
+ into the derived parser.
+
+To run the example on the sample XML instance document simply
+execute:
+
+$ ./driver instance.xml
