After careful consideration I vote "no" on the proposed new CIF syntax, although I agree with the general direction. I'm deeply concerned about introducing new syntax for delimiting strings without solving a long-standing problem. James explained to me that the "extra multi-line text delimiters are provided to further reduce the likelihood of running into text that is impossible to delimit." I strongly believe that the problem needs to be solved completely, for example by adopting the widely used backslash escape semantics. I would agree to the proposal after either - an escape mechanism for the new triple-quoted strings is added or alternatively - the new triple-quote syntax is removed, so that it can be introduced later with an associated escape mechanism.
