- Add test task using Woodstox for XML serialization
- Delete duplicate test relying on implementation details
- Use Unicode replacement character for illegal characters
- Add test for whitespace escaping
- Implement workaround for escaping whitespace chars in attribute values
Rather than double-escaped character references.
