As Sergei and Rob notes, the bank compatible properties look
a bit strange. Especially if they are all the same essentially.

I like Sergei's idea to simply use the reg property if what you want
is really a unique ID number. What do you think about this?

I think the 'reg' property makes more sense, yes. I'll fix this in the 
v5, this
week-end. Do you think it can go in 4.12?

Thanks,
