This is a "Hello, world!" example that shows how to use the 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 the 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
