My purpose was to check something I was sure of, which was working on my Sony to see if I could trust this validation tool and not he other way around.
My previous trials at W3C for validation software had been a little disappointing because they brought me back lots of clueless details that I could'nt exploit.
So, FlightCrew seems to be an exploitable no-nonsense tool and of course, do not misunderstand me, W2E is a very good epub software producer.
