+This directory contains a number of examples that show how to serialize
+the object model into a number of predefined and custom binary formats.
+The following list gives an overview of each example:
+
+boost
+ Shows how to save/load the object model to/from a custom format
+ using the Boost serialization library as an example.
+
+cdr
+ Shows how to save/load the object model to/from CDR (Common Data
+ Representation) binary format using ACE CDR streams.
+
+xdr
+ Shows how to save/load the object model to/from XDR (eXternal Data
+ Representation) binary format using the XDR API provided as part of
+ Sun RPC.

+This example shows how to save/load the object model to/from a custom
+format using the Boost serialization library as an example. You will
+need the Boost serialization library[1] installed in order to build
+and run this example.
+
+[1] http://www.boost.org
+
+The example consists of the following files:
+
+library.xsd
+ XML Schema which describes a library of books.
+
+library.xml
+ Sample XML instance document.
+
+boost-archive-extraction.hxx
+boost-archive-insertion.hxx
+ Boost archive insertion and extraction operators for fundamental
+ types. You will need to provide a similar set of operators for
+ your own stream types.
+
+library-prologue.hxx
+ Contains a number of #include directives that are inserted into
+ the generated code by the XSD compiler. The included files are:
+ boost/archive/text_oarchive.hpp, boost/archive/text_oarchive.hpp,
+ boost-archive-insertion.hxx, and boost-archive-insertion.hxx.
+
+library.hxx
+library.cxx
+ C++ types that represent the given vocabulary as well as Boost
+ archive insertion and extraction operations. These are generated
+ by the XSD compiler from library.xsd. The --hxx-prologue-file
+ option is used to insert the contents of the library-prologue.hxx
+ file into the generated header file. The --generate-insertion and
+ --generate-extraction options are used to generate the insertion
+ and extraction operations for text_oarchive and text_iarchive
+ types.
+
+driver.cxx
+ Driver for the example. It first calls one of the parsing functions
+ that constructs the object model from the input XML file. It then
+ saves the object model to text_oarchive and loads it back from
+ text_iarchive. Additionally, it prints the resulting text
+ representation as well as the content of the object model before
+ saving it to text_oarchive and after loading it from text_iarchive.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver library.xml

+This example shows how to save/load the object model to/from CDR
+(Common Data Representation) binary format using ACE CDR streams.
+Support for other data representation streams can be easily added. You
+will need the ACE library[1] installed in order to build and run this
+example.
+
+[1] http://www.cs.wustl.edu/~schmidt/ACE.html
+
+The example consists of the following files:
+
+library.xsd
+ XML Schema which describes a library of books.
+
+library.xml
+ Sample XML instance document.
+
+library.hxx
+library.cxx
+ C++ types that represent the given vocabulary as well as data
+ representation stream insertion and extraction operations. These
+ are generated by XSD from library.xsd. Note that the
+ --generate-insertion and --generate-extraction options are used
+ to generate the insertion and extraction operations for ACE CDR
+ stream.
+
+driver.cxx
+ Driver for the example. It first calls one of the parsing functions
+ that constructs the object model from the input XML file. It then
+ saves the object model to ACE_OuputCDR and loads it back from
+ ACE_InputCDR. Additionally, it prints the resulting binary
+ representation as well as the content of the object model before
+ saving it to the CDR stream and after loading it from the CDR stream.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver library.xml

+This example shows how to save/load the object model to/from XDR
+(eXternal Data Representation) binary format using XDR streams.
+The XDR API is available out of the box on most UNIX and GNU/Linux
+systems as part of Sun RPC. On Windows you may need to install a
+third-party library which provides the XDR API.
+
+The example consists of the following files:
+
+library.xsd
+ XML Schema which describes a library of books.
+
+library.xml
+ Sample XML instance document.
+
+library.hxx
+library.cxx

+ stream.

+ that constructs the object model from the input XML file. It then
+ saves the object model to the XDR representation and loads it back.
+ Additionally, it prints the content of the object model before saving
+ it to the XDR representation and after loading it from the XDR
+ representation.
+
+To run the example on the sample XML instance document simply execute:
