I am not familiar with the current state of Pat's model, which I
understand has been the subject of an off-list discussion. Are details of
the ReferenceSystem object available anywhere?

I agree with you that simple is better, so long as we are confident
that the simple model can be expanded later to meet more complex
requirements. Sometimes you need to think very hard even about simple
models to make sure they will not limit what you can do later on.

Apologies for previous long messages. I used many words to try to make my
meaning clear. Maybe I did not succeed very well!
