Well, it's the thread that just won't end. I'm afraid I have one more thing to add to this discussion.
Should the [simbraille]e[/simbraille] in [simbraille]0<&oe[/simbraille] actually be [simbraille]s[/simbraille] because it is a SIGMA?
We were revisiting this for QC purposes, and this question finally occurred to us.
Thank you, again, for your time and help.
