[Fedora-packaging] package naming -- axis2 version 1.4

Another bizarre package naming question from the java world: Axis2 version 1.4 and version 1.6 seem to generate very different code from WSDLs. During the Fedora 17 cycle, I packaged 1.6 simply because it was latest, and I hoped that I could make it work for my needs. I have not been able to, and so I'd like to contribute a version 1.4 package for compatibility. However, I have no idea how to go about naming a package like this. The official upstream project is "Axis2", and the normal scheme would be confusing ("axis214"). I could use something like "axis2v14". Any thoughts or recommendations on this? Thanks. Andy
