Did you mean "apparently working but *non*-standards conforming"?

Other than that, seems to be a sane application of "Be conservative in what you
send".  Our network is some 30K cat-5 ports, 1100 switches, 1300 wireless
access points, and we appreciate it every time somebody makes things more
bulletproof.  And yes, we prefer things to out-and-out *fail* rather than
run in a wonky configuration - hard failures usually get fixed in a few
minutes, wonkiness can drag on for months of mystifying symptoms...
