    You are right. Books Online has it wrong.
    mk:@MSITStore:C:\Program%20Files\Microsoft%20SQL%20Server\80\Tools\Books\architec.chm::/8_ar_da_0777.htm

    SQL Server follows the ANSI / ISO Standard behaviour for CHECK and FOREIGN
    KEY constraints: values that are *not FALSE* are permitted. I think it's
    safe to assume that the designers' intention was that this should be the
    case and that Books Online is in error :-).
