This example shows how to handle "type-less content" such as mixed content
models, xsd:anyType/xsd:anySimpleType, and xsd:any/xsd:anyAttribute in
the C++/Parser mapping.

In this example we use mixed content model to describe text with embedded
links, e.g.,

  This paragraph talks about <a href="uri">time</a>.

The example transforms such text into plain text with references, e.g.,

  This paragraph talks about time[0].

  [0] uri

The example consist of the following files:

text.xsd
  XML Schema which describes "text with links" instance documents.

text.xml
  Sample XML instance document.

text.hxx
text.txx
  Parser templates generated by xsd from hello.xsd.

driver.cxx
  A parser implementation and a driver for the example. The parser
  implementation prints the transformed text to STDOUT. The driver
  first constructs a parser instance from the parser implementation
  mentioned above and a couple of predefined parsers for the XML
  Schema built-in types. In then invokes this parser instance to
  parse the input file.

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

$ ./driver text.xml
