Well, if "The recursive table" includes references to columns in it, then this rule is broken in the first example given in section 3.1
```
WITH RECURSIVE
cnt(x) AS (VALUES(1) UNION ALL SELECT x+1 FROM cnt WHERE x<1000000)
SELECT x FROM cnt;
```
where "x" appears twice *outside* the FROM clause
If I remove the "cnt." from my example
```
WITH RECURSIVE
cnt ( x , list , done , Pagelist ) AS (
VALUES ( 1 , 1 , 0 , '' ) UNION ALL
SELECT x + 1 AS x ,
( list || ',' || ( cnt.x + 1 ) ) AS list,
( x == 9 ) AS done ,
( SELECT Page FROM GetreuerMusicMeister LIMIT x ) AS Pagelist
FROM cnt WHERE x < 10
)
SELECT list , Pagelist FROM cnt WHERE done == 1 ;
```
it still doesn't work, but the error message refers to "x" rather than "cnt.x".
So the rule seems to be applied more strictly in subqueries.
