+This example shows how to access the underlying DOM nodes in the
+C++/Tree mapping in order to handle raw, "type-less content" such
+as mixed content models, anyType/anySimpleType, and any/anyAttribute.
+
+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.
+
+text.hxx
+text.cxx
+ C++ types that represent the given vocabulary and a set of parsing
+ functions that convert XML instance documents to a tree-like in-memory
+ object model. These are generated by XSD from text.xsd.
+
+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 uses
+ both the underlying DOM and statically-typed mapping to perform the
+ transformation.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver text.xml
