That it was implicitly covered does not mean it's not unambiguous to the reader.
Brian and I definitely weren't sure. Fwiw, I think this is the kind of paragraph 
that should either include quick one-line examples of valid syntax demonstrating what 
the prose is talking about. Failing that, covering each case explicitly, while more verbose,
would be clearer.
