Re: Resolution needed: ISSUE-165: datatype map

Hello Guus, all,

I'm afraid to say that nothing has changed for me. Rather, after the 
last mail exchange between Pat and myself, which brought some (to me) 
surprising answers, I am now even more convinced that this change must 
not make its way into the final standard. I still consider it a 
substantial technical change rather than an editorial change, its 
formulation (even with the new textual changes) to be very confusing 
compared to the original version which I consider very clear, and I 
still do not see any need or motivation for the change to be made.

I do not see a requirement to restate my reasons for my objection, as I 
have stated them already in considerable detail in my previous mails.

Best regards,
