 Hi Jim,

 You're absolutely right, I was a bit loose in my terms. But sometimes you
 don't know where you are with respect to MSL - a local sea level may be
 all you have. In this case "local sea level" is still the datum, albeit
 not one that you can easily convert to another CRS. It's still the zero
 point of your referencing system.

 (Sorry, we are probably getting a bit off topic from the original
 discussion.)

 Cheers,
 Jon
