The only difference between what Geir Ove proposes and my normal
modeling practice is that in my practice the prose descriptions of the
model (the "infoset") is literally bound to the UML classes and packages
in the source data for the model. Otherwise, they are equivalent, I
believe.

What do try to do is limit the prose to that necessary to say things not
already said by the graphical components of the model or the
formally-stated constraints or descriptions of things that are not
obvious from the model (for example, pointing out that certain important
derived relations are in fact derivable, something that could be puzzled
out from the model but that might not be obvious to the typical reader).

Cheers,

E.
