Please have a look at our forum, where I proposed a visualization for such cases already!

For my understanding, "update" presumes the existence of the artifact to be updated. Furthermore, in order to prevent island solutions for very specific cases, please consider the proposed notations in the forum and carefully consider different cases and combinations that can occur. It took me some time to find a valid and predominantly consistent visualization, so I would be happy if you either improve the proposed notation or consistently change it as a whole. regards, Stefan > > Ciao, > Christian > > On 09/26/11 12:51, Christian Krause wrote: >> Of course.
