Doesn't sound too flexible. It'd be great if I could add fields to the 
product record. If I use a field prefix there should be no clash. I only 
need a way to tell the shop I have some more fields to render/process.

ISBN looks general enough, but I prefer it if an extension is extensible so 
I can make local changes that are upgrade-safe. eg in the Core I can add 
fields to be stored in the rootline.
