Re: [mdr-users] Clustering the UML for Traceability

You can see the clustered import e.g. in extension file for UML 1.3: 
http://mdr.netbeans.org/source/browse/~checkout~/mdr/xmidiffs/01-12-02_Diff.xml

There is a new package UML that clusters the top-level packages from the 
UML 1.3 metamodel and adds JMI tags to them.

Martin
