That's not quite my interpretation. I believe the most recently revised response header proposal from Tom [1] uses Tk:1 to indicate compliance with the third-party requirements in the Compliance spec, but doesn't indicate that no identifiable data is retained at all (maybe it's retained for a security/fraud exception, for example).

I agree that the text should ultimately be replaced by a pointer to the Compliance spec, but I think it should be to the outcome of ISSUE-119, rather than just to third-party compliance. Tk:n would have a distinct meaning from Tk:1, but we can come back to it when we discuss ISSUE-119 rather than right now if that's simpler.

Thanks,
Nick
