Hi Kent, Yeah - I realize that I'm jumping ahead of where we are. I'm a bit worried that we're making forward looking assumptions that we'll be able to stick to those constraints that we're defining in revised-datastores, and we may find that difficult later. For this specific issue I suppose there is at least the possibility that we *could* have a common schema (and have operational be a superset). Rgds, Jason
