Adding Dirk for second vote.
Approved by Dirk & Kai.
The fundamental problem is that the projection viewer has no way to distinguish between annotations that have been deleted during the self-cleanup of the annotation model (i.e. because of a document change) and those that have been deleted by clients of the annotation model such as the provider of the projection structure. This is something that we have to add post 3.0. For now the workaround is to reinitialze the projection document from scratch if problems occur during the incremental update.
