Some additional aspects to consider:

* Introduce a dedicated ultra root node which serves as a kind of view handle. We should not just have a implicit root block as we always have to account for the case that it might be replaced by a parser or pretty printer action. An explicit root block will help us to maintain the references to a TextBlocks model even if we need to drop/replace a TextBlock because it has been deleted and/or replaced by a new one.

* Alternatives should be encoded with real references and not by a list of positive and negative integers.

* We have to introduce status information about partiality. As of now, the pretty printer cannot know whether an element is not represented within a TB model because it was left out on purpose, or because it was only created after the TB model has initially been created. 

* There is potential to simplify the corresponding/referencesElements references as discussed before.
