+This example shows how to create an XML document by performing multiple
+serializations of its smaller parts. This can be useful when the
+document is too large to fit into memory or when the other end needs
+to start processing without waiting for the whole document (streaming).
+
+The example consists of the following files:
+
+records.xsd
+  XML Schema which describes a collection of data records.
+
+records.hxx
+records.cxx
+  C++ types that represent the given vocabulary as well as serialization
+  functions. These are generated by XSD from records.xsd.
+
+driver.cxx
+  Driver for the example. It progressively serializes one thousand data
+  record into a file (out.xml).
+
+To run the example simply execute:
+
+$ ./driver
