This is a "Hello, world!" example that shows how to use C++/Tree mapping
to access XML instance documents described by XML Schema definitions.


The example consist of the following files:


hello.xsd
  XML Schema which describes "hello" instance documents.


hello.xml
  Sample XML instance document.


hello.hxx
hello.cxx
  Data types that represent the given vocabulary and a set of parsing
  functions that convert XML instance documents to a tree-like in-memory
  data structure. These are generated by xsd from hello.xsd.


driver.cxx
  Driver for the example. It first calls one of the parsing functions
  that constructs the in-memory representation from an input file. It
  then prints the content of the in-memory representation to STDERR.


To run the example on the sample XML instance document simply execute

$ ./driver hello.xml
