Incorrect, MDA tools don't and can't regenerate higher level models from
lower level models. The mappings realised by the transformations in MDA
tools only have a unique inverse mapping in the trivial case.

This is the trivial case where the level of abstraction of your model is the
same as the level of abstraction of your code.
In any case, your general questions are probably better posted on a group
such as http://groups.yahoo.com/group/mda-discussion/ rather than the gmt
developers' mailing list.
