> It seems that a query like
> {noformat}
> SELECT * FROM [nt:base] WHERE [a/b] IS NULL
> {noformat}
> should return paths where there exists a child {{a}} without a property {{b}} (this works as expected)
> But, it should also return paths where there is not child {{a}} in the first place.
> [~tmueller], does this sound a reasonable expectation?
