I would opt for changing the title and summary of the BP to fit to the
latest discussions instead of superseeding this with a new BP. If you
agree, I will take a first pass tomorrow and we can iterate over it.
Makes sense to make this BP dependent on the DSL BP as a pre-req. We would
probably keep the TOSCA (or additional formats) translation BP on hold and
focus on the DSL and its implementation for now and then see what we can
achieve on top and when.

Ok for everyone?
