This is great news. Now, whenever I want to do something that is
prohibited by code, I can just say that the Code Making Panel is gonna
correct that pesky code section (<i>insert your problem citation
here</i>) any day now, so I might as well be allowed to do whatever it
was I was fixin' to do anyway. Unless I am missing
something...<br><br>
Thanks!<br><br>
