Hi Matthias,

(This is probably starting to bore you:) you can write several small 
transformation modules and then superimpose them in any order, provided 
that there's no rule overlap.

The resulting transformation will be the union of all transformation 
rules, helpers, input and output models and meta-models. You only need 
to make sure you provide all the parts in your launch configuration.

This approach will probably work as well, but is more difficult to 
implement ;-). It also creates more compiler overhead, since it requires 
transforming the affected transformation modules and then recompile them 
as one single module.
