Enigma Source (svn, archived)

- Xerces initialization added;
- DOM error handler added (logging only);
- utf conversions added (to be completed);
- namespace workarounds (file.cc);
- started doxygen commenting additions;

Note: - a Xerces version as described in the docs is now mandatory to compile!
- in main.cc I added an outcommented (temporary) hook to testXerces() that
allows you to test Xerces and validate a XML file (schema or dtd based).
