We do have an interface, 
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/projects/microcontainer/trunk/deployers-structure-spi/src/main/org/jboss/deployers/structure/spi/classloading/Version.java?revision=64469&view=markup
but you still need an implementation.
Currently, we use the OSGi version class as our implementation:
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/projects/microcontainer/trunk/deployers-structure-spi/src/main/org/jboss/deployers/structure/spi/classloading/helpers/VersionImpl.java?revision=64482&view=markup

There was a previous discuss on this problem.
The issue is basically if we don't use the OSGi version then we have
to come up with some complicated code that handles comparisons between
the different implementations when doing compareTo().
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/projects/microcontainer/trunk/deployers-structure-spi/src/main/org/jboss/deployers/structure/spi/classloading/VersionRange.java?revision=64469&view=markup

Of course, its probably not a real problem in practice since it is unlikely that
foo:1.0.0 uses a different version implementation to foo:1.0.1 or foo:2.0.0 :-)
