Well, rip-123 will always be correctly addressed as ripe-123. It's just that ripe- doc-1234 would could be called ripe-1234. I don't see any confusion arising from that and the normal document churn would take care of any potential confusion, anyway.
The confusion is that, for the next 25 years or so, people will be wondering what the relation is between ripe-<foo> and ripe-doc-<bar> documents. Which one replaces which other one? So again, please don't. Remco This email is from Equinix Europe Limited or one of its associated/subsidiary companies.
