I've actually already done almost all the work for converting BETWEEN to a node but I have a couple of questions: Should I use a boolean in the node to indicate whether it is SYMMETRIC or ASYMMETRIC, or should I use some sort of integer to indicate whether it is SYMMETRIC, ASYMMETRIC or DEFAULT (ASYMMETRIC). That way the reverse in rules and views could leave out the ASYMMETRIC if it wasn't specified originally, rather than always adding it in. Which is better?
