the example is too overwhelming, one or two should be enough?

Agreed, fixed in the upcoming v5.  The four outputs are actually two equivalent pairs so I framed them up as such and removed two of the results.


5.2.7.3. Single-Column Subquery Rows.
two examples, can be reduced to one.

Disagree, the fact that the two outputs are different is precisely the point of having the two queries.  I could see an argument for removing both, given the pair outputs are indeed the same pair in the previous sect3.  But since they are separate sect3s I'm inclined to keep this intact.


"does not support...does not include" double negation, can we make it
"positive".
"not null constraints." should be "not-null constraints"?

I've also reworked this for v5
