Well, we need to collect all the aspects of the problem together, and
start seeing which are logically incompatible. Then it becomes a
(NP-complete) 3-sat problem ;) ;) ;)

Not yet, but will soon be, as it's needed for mail raster.

Actually, I just had a really strange idea: why not make selectors be
simply inverse paths... that would make a lot of sense in some ways.

So when the way from the child to the parent is step here, headcell here,
step there, then the selector would be the inverse (automatically: the
same path definition in the structure would be used): step -there,
all cells poswards from here, step -here.

It's a nice idea but I don't know whether it'll work.
