That is correct. No “shall” in recommended practice. And WG14’s guidance is no “shall" in anything other than constraints as a general rule (exceptions always exist) going forward and even backwards (the UB study group is looking to remove these in other areas)!</div>

In C2Y, we never use 'shall' in clauses which are Recommended Practice.<br>
<br>
I assume that is an ISO rule.<br>
<br>
Just after an answer. No need to put this into the next meetings topics<br>
for discussion.<br>
<br>
Thanks - Damian<br>
