I may or may not be ahead of myself, please forgive me if so. I've use the full Maven treatment to set up a release candidate for 1.4.3, and then kludged slightly to achieve the parallel set of zip 'dist' files. I now realize how I could do this more cleanly next time around the bend.
Anyway, http://people.apache.org/~bimargulies/maven_staging is a maven repo with just exactly what would release if you all love this attempt. It's got checksums, signatures, 8-by-10 color glossies, the works. http://people.apache.org/~bimargulies/xmlschema-1.4.3-dist , on the other hand, has ZIP files with RC1 in their names. In the event of a happy vote, I'll regen these without the RC1 tag and that will be what pushes out. Since this used the full maven mechanism, it checked in a version of the POM that says '1.4.3', it made a tag for that, and then it checked in another version that put it back to SNAPSHOT.
