+This example shows how to parse the XML data matched by XML Schema
+wildcards (any and anyAttribute) in the C++/Parser mapping. The
+example consists of the following files:
+
+email.xsd
+ XML Schema which describes a simple email format with the
+ extensible envelope type.
+
+email.xml
+ Sample email message.
+
+email-pskel.hxx
+email-pskel.cxx
+ Parser skeletons generated by XSD from email.xsd.
+
+driver.cxx
+ Parser implementations and a driver for the example. The
+ parser implementations simply print the data to STDERR.
+ The driver first constructs parser instances from the
+ parser implementations mentioned above and a couple of
+ predefined parsers for the XML Schema built-in types.
+ In then invokes the parser instances to parse the input
+ file.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver email.xml
