Whatever happened to "railroad diagrams" like this one?
I always liked these, maybe because I learned Pascal at an early age.
David Geary and I use them in our Core

I just wrote up a description of the @OrderBy annotation in
Persistence Architecture, and I ran across the following description
in the spec:
orderby_list::= orderby_item [,orderby_item]*
orderby_item::= property_or_field_name [ASC | DESC]
This describes what you can have in the value attribute,
@OrderBy(value="name, score DESC")
I wasted a whole day tweaking

over, or do railroad diagrams still have their place? Do you have any
recommendations for drawing tools?
