Handle consequences of change of sharing mode for other users
The following is expected behaviour in terms of sharing modes but it has an impact on other users we should maybe discuss at some point.
When someone else has used my topic types in their own workspace and I decide to switch my workspace (containing those types) to private, then the other person obviously cannot use my type definitions any more. But: This leads to the fact that their topicmap does not load at all without any feedback (apart from the log file).
Apparently there are two distinct cases for which need to discuss how DMX should support them. Please try to address them both accordingly in your comment.
Case A) "Opening content": Consequence of opening up a workspace (increasing sharing mode).
Case B) "Privatizing content": Consequence of decreasing a workspace SharingMode into e.g. a "Private Workspace".
