You can use version properties like this:

   <properties>
      <version.foo.bar.baz>1.2.0.GA</version.foo.bar.baz>
   </properties>

Then you can refer to it later (I think in children as well) as 
${version.foo.bar.baz}.  This gives you a single point where the version 
can be set.  (Even if I'm wrong about the parent/child thing, since the 
version is on the same line as the property name, search/replace can be 
more specific.)
