FUML15 — fUML should include association classes

While the fUML subset includes classes and associations, it currently does not include association classes. The original reason for this was that association classes can always be simulated using just regular classes, and keeping associations separate from classes made the fUML execution model simpler. However, when one uses a class instead of an association class, the effective end multiplicities do not reflect the association multiplicities, so the model is less clear. Therefore, it would be preferable to support association classes directly, along with the relevant link object actions on them.

Out of scope

The RTF has decided that this to large a change to the scope of fuml to be handled in the RTF process. Adding this capability to fUML would be better handled by an RFC or RFP process.
