Rose (<=2000, anyway) doesn't bolden the borders of active classes.

You can probably make a good stab at mapping UML facilities onto
tasks, but there's a considerable mismatch. I guess it depends whether
you think the model should be constrained by the target
architecture. For example, do you ban operations that return values
(functions)? or do you provide some more complex mapping so that when
the analyst says "function" you know how to represent it?
