The [size=13]UML 2.1 Superstructure (interim)[/size] (http://www.omg.org/cgi-bin/doc?ptc/2006-04-02) Specification, implies that both vertexes, edges and features are derivable. (Certainly if you look at 7.3.3 Association (from Kernel), you'll see Associations are derivable via isDerived)
EA currently doesn't support this. In my view, anything that can be modelled is, essentially, derivable.
I'd like EA to add the [ ] Derived checkbox to any EAElement or EAConnector or EAFeature.
Thoughts? Votes?
