Am a little further along, now. Turns out I was, uh, "unplugged" and
reviewing a *copy* of my XML output that wasn't being refreshed by
reprocessing the map template. Duh. The namest, nameend, and morerows are
all working now. Funny how stuff like that helps 😉
The correct (well, one set of correct) settings are:
@namest != @nameend
@morerows != 0
Oh, and FWIW, 1=0 on colname. Don't need that attr ever, I don't think.
