Hi Simon, I was wondering why an account must be from one source. I think a source maybe an annotation on an account. I think a more general definition would be. - An account is a record of something that has occurred from a particular perspective. I agree with the notion that every description of some occurrence must be part of an account but I don't think that needs to be identified. thoughts?
