The xml schema is not finished yet, but will follow shortly.
The changes to the layout document are mostly cosmetic. We tried to
include some UML diagrams to make it more readable.
The render document has quite some changes, cosmetic as well as content.
The main changes are probable the way text is handled and the
possibility to position render objects relative to each other.
We also added some 2D shapes to start with, more will follow if needed.
We tried to include all the suggestions that have been made so far and
hope the there will again be lots of feedback.
