In case you are not aware, VTD-XML 2.11 and 2.12 are also available on Maven Repository. They are available at http://mvnrepository.com/artifact/com.ximpleware/vtd-xml
Unlike Sourceforge or Github, the maven repository hosts only snapshots of VTD-XML at the point of releases for only the Java platform. With sourceforge's CVS you got a complete, history of entire source base, as well as most up to the minute update, for the whole range of supported platforms.
