+This example shows how to handle raw, "type-less content" such as
+mixed content models, anyType/anySimpleType, and any/anyAttribute
+in the C++/Parser mapping.
+
+In this example we use mixed content model to describe text
+with embedded links, e.g.,
+
+ This paragraph talks about <a href="uri">time</a>.
+
+The example transforms such text into plain text with
+references, e.g.,
+
+ This paragraph talks about time[0].
+
+ [0] uri
+
+The example consists of the following files:
+
+text.xsd
+ XML Schema which describes "text with links" instance
+ documents.
+
+text.xml
+ Sample XML instance document.
+
+anchor.hxx
+ Anchor type that captures the information about a link.
+
+text.map
+ Type map. It maps XML Schema anchor types defined in
+ text.xsd to C++ anchor class defined in anchor.hxx.
+
+text-pskel.hxx
+text-pskel.cxx
+ Parser skeletons generated by XSD from text.xsd and
+ text.map.
+
+driver.cxx
+ A parser implementation and a driver for the example. The
+ parser implementation prints the transformed text to STDOUT.
+ The driver first constructs a parser instance from the parser
+ implementation mentioned above and a couple of predefined
+ parsers for the XML Schema built-in types. In then invokes
+ this parser instance to parse the input file.
+
+To run the example on the sample XML instance document simply
+execute:
+
+$ ./driver text.xml
