Status quo:
If you have something truly empty, you can go to anything; mixed or not.
If you have something which is mixed but allows no element children, you
can go to sequence and mixed, and choice and mixed, but not to all and
mixed.

MSM's instinct is to fix non-orthogonality by removing the special-case
for all, which is probably too much trouble right now. Don't like
repairing non-orthogonality by adding more special rules.

MK: One thing we could do is remove special case for empty all, which
removes that point of non-orthogonality.
MSM: Could then just replace rules that appeal to empty sequence to
apply to empty all as well.
MK: But variety empty=empty sequence.

SG: Think there is no real problem here. Think any change is risky.

Agreement, or acceptance of this view.
