I tried to relate domains using Links between Ports but that does not 
look good to me (see the attachment). If I have bidirectional ports a 
link between does not have to be bidirectional. But to connect them I 
use sink/source structure that indicates direction (source->sink). Is 
there a solution for that already discussed?
