I've never seen these exceptions recorded either. :-)
I think the most significant, frequently unrecorded, change is when the
instruments used for fore shots switch with the ones making back shots.
Now if you are going back to correct for systematic instrument error, you
will be correcting the wrong set of instruments. Obviously, there is no
data standard that can help in this situation. It is just one more thing
the sketcher needs to note. (Perhaps a place in the form next to the
fore/back shot reading for the instrument ID, as if that form wasn't busy
enough already.)

I thought that's what the splat meant, but I am no DTD syntax expert, and
the comment said "one or more".
