Hi Jan..
I guess you are referring to the XOR constraint between associations. That
is, there is a link to an instance of one class or another, but not both.
You can show this as a dependency between the two associations. Name the
dependency {xor}.
Note that I used the expression "show" rather than "model" as Rose ignores
this dependency as far as code generation is concerned. It is a visual clue
for the developers only. The attributes will be generated for both
associations (which is correct). You will need to manually manage the code
that ensures the exclusivity.
Best regards,
