Actually, a number of standards bodies have found, to their chagrin, that test suites that are developed and.or certified by the standards body are a terrible idea. The problem is that they become the real standard, substituting "passes the test suite" for "conformance to the standard" or the IETF's long tradition of "interoperates successfully in practice". And we have never had a global requirement for "two implementations to proceed to rfc". john
