Re: [tei-council] Recommendations on values of @xml:id (FR #540)

"A check digit is a form of redundancy check used for error detection on identification numbers“ [1] It simply adds one digit to your ID which gets computed from the base ID. So, if your base ID is „HOL01“, the ID with check digit would be e.g. „HOL012“. This is the only one you’ll use thereafter because the check digit can validate your ID string. If you e.g. swap digits and put „HOL021“ anywhere by accident you are able to detect this error. Best Peter [1] https://en.wikipedia.org/wiki/Check_digit

I also didn't add anything about check digits, because I admit --and I tried-- I can't understand how they work :) Maybe Peter could add a sentence or two?
