Configurable version in artifactId

[Mathieu Malaterre]

Hi Emmanuel,

I believe I understand now why mh_make was getting confused all along
with junit4/xmlgraphics-commons. It turns out that fop made the
version of those configurable from the top-level parent to the
children, eg:

$ cd fop
$ cat fop-events/pom.xml
...
    <dependency>
      <groupId>org.apache.xmlgraphics</groupId>
      <artifactId>xmlgraphics-commons</artifactId>
      <version>${xmlgraphics.commons.version}</version>
    </dependency>
    <!-- test-only deps -->
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>${junit.version}</version>
      <scope>test</scope>
    </dependency>
...

What would you recommend in this case ?

Thanks,
