> The current documentation doesn't mention that we allow the window definition
> to be explicit.
> The restriction on WHERE clause no longer applies, nor does the sentence
> about ORDER BY not being allowed in subqueries. Cf. rreffuncrownumber.dita.
> Also, the documentation mentions that we don't support LIMIT, but not that we
> now support the FETCH/OFFSET clause, which is often a better option than
> ROW_NUMBER.
