I'm having two different models (they have the same information, but a
different structure) and want to transform one model into the other one.
Does this work with Ecore2XML? I tried it but it's always output = input.
Is there anything I have to consider? Does it work when having two
different models (including their code)?

Matthias,
The approach doesn't work well if simple mapping of feature names and
type names doesn't accomplish most of the goal. In that case, you'd
probably want to read in with model and then transform the data from an
instance of the one model to an instance of the other model.
