-This example shows how to embed the binary representation of the schema
-grammar into an application and then use it with the C++/Tree mapping to 
-parse and validate XML documents. This example is similar to the 'caching'
-example except that it loads the binary representation of the schemas
-embedded into the application instead of pre-parsing external schema files.
-
-The example consists of the following files:
-
-xsdbin.cxx
-  Tool for converting one or more XML Schema files to the compressed binary
-  representation. The output is written as a pair of C++ source files 
-  containing the array with the binary data. Use the --help option to see
-  the tool's usage information.
-
-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 and a set of parsing
-  functions that convert XML instance documents to a tree-like in-memory
-  object model. These are generated by the XSD compiler from library.xsd.
-
-library-schema.hxx
-library-schema.cxx
-  Binary representation of the library.xsd schema. These files are generated
-  by the xsdbin tool.
-
-grammar-input-stream.hxx
-grammar-input-stream.cxx
-  Input stream implementation with the special-purpose schema grammar 
-  decompression algorithm. It is used to load the binary schema representation
-  produced by the xsdbin tool.
-
-driver.cxx
-  Driver for the example. It first sets up the Xerces-C++ DOM parser and
-  loads the embedded binary schema grammar for validation. It then performs
-  ten iterations that parse the input file to a DOM document using the DOM
-  parser and call one of the parsing functions that constructs the object
-  model from this DOM document. On each iteration the driver prints a number
-  of books in the object model to STDERR.
-
-To run the example on the sample XML instance document simply execute:
-
-$ ./driver library.xml
