* The model builder is the second stage in the layout process.

* this model is already bound to the constraints of the underlying renderer.
*
* Each generated element has information on which logical page it will be
* rendered (by looking at the page style name); depending on the output target,
* it might even know the physical page already (including the page number).
* (The PageInformation is initiated by the Normalizer.)
*
* The ModelBuilder is responsible to manage the moved content.
