fabric8-maven-plugin: unable to configure for more complex wrap url handler syntax.

Issue

The fabric8-maven-plugin can be configured to add additional bundles to the profile created by this plug-in.
E.g. one can set properties for this plug-in like

 <properties>
   <fabric8.profile>testprofile</fabric8.profile>
   <fabric8.bundles>
      ...
   </fabric8.bundles>
 </properties>

However how can one specify a bundle using wrap: url handler while also explicitly configuring the bundle's Export-Package list, the Bundle-SymbolicName and Bundle-Version as in this example?

<fabric8.bundles>
  wrap:mvn:org.apache.tomcat/juli/6.0.36;$Bundle-SymbolicName=juli&amp;Bundle-Version=6.0.36&amp;Export-Package=org.apache.juli;version=6.0.36,org.apache.juli.logging;version=6.0.36
</fabric8.bundles>
