Since there wasn't a decent XML parser, I've started writing one myself. Main
features:
* Allows 100% round-tripping, even for weird whitespace between attributes
in the start tag or in the end tag
* Suitable for building editors and filters which want/need to preserve
the original file layout as much as possible
* Error messages have line and column information
* Easy to reuse individual components
* XML 1.0 compatible
Needs Java 5 or better.
