I think the reason this keeps coming up, is that the IETF documents are usually referenced by number rather than title. So you'd say that your system is compliant with RFC 5280 rather than saying that it is compliant with "Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile". In other organizations, like the W3C, documents are referred to by name. So "Content Security Policy 1.0" is called that when it's proposed, when it's discussed, and when it's published. Even a later revision might be called "Content Security Policy 1.1", so version numbers, while they exist and are accessible, are mostly hidden from the users. Yoav
