Do you know <natural-id> ?
No I hadn't seen that before, but thanks that looks useful. I'm not sure if I can implement that in fluent's conventions though, but perhaps I can. Not that I am married to fluent, I will likely output the configuration to HBM's at some point.
Looks like there isn't support for that yet: code.google.com/.../detail
Any idea how you would get some automapped Index creation on a JoinedSubClass?
IJoinedSubclassInstance does not contain an Index() method
