I would have been able to predict that :-)

No they must not.
They can be written in natural language first
I am thinking 'conceptual' representation too, in terms of diagrams,
factsheets, (maybe that exists already - I may have not taken vision of that
yet)

I am asking if there is a spec or any uptodate documentation to support your
understanding/assumption, so that we can discuss further in a better
informed way
didnt you say there is something broken? can you point us?
