eg: SYD-xNRT-JFK-xDFW-BNE would be Sydney-New York via Tokyo, returning to Brisbane via Dallas. It could also be written as -oJFK-.
Even better is to use lower case for transits and UPPER CASE for stops: SYD-nrt-JFK-dfw-BNE. The advantage of this system is that the entire string (which can sometimes be quite lengthy) can simply be cut-and-pasted into a tool such as the GCM or Mileage Monkey without the need for tedious deletion of extraneous characters. When you are asking someone for help with a routing, you want to make it as easy for them as possible.
