Step diagrams are what lawyers call flow charts, but with a design convention language that's a bit like UML, and with tons of meta data attached to each element. There's also a time dimension as you can step through to see each stage of a legal process. I understand what they are as a dev but I'm not a lawyer so I can't point you to anything more unfortunately.
