Wouldn't the CXF version imply the plugin version? Unless they can be 
updated independently in the field after release. In which case, you'd 
end up with the same situation that Linux distributions have, which 
seems to work. This is the nature of modules.

 From my [outsider] point of view, releasing new versions of unchanged 
modules just to keep their version numbers in sync seems to defeat some 
of the reasons of having separate modules in the first place (i.e., 
avoiding unnecessary recompiling and repackaging).
