The "or" conditional element is something I'm promised to add for a
while. It requires some structural changes that are trickier than
you'd think (at least, so far, trickier than I've been able to clearly
lay out.) Until then, as a user suggested, multiple rules are the only
way to alternate patterns; alternatives within a single slot can use
the "or" function or the '|' predicate constraint (see 5.0a6 Manual
section 2.8.1).
