Dag H. Wanvik commented on DERBY-6103:
--------------------------------------

Thanks, Kim! I agree you don't need to use all of those adjectives, so:

> If you choose to use an explicit WINDOW clause in a SelectExpression instead 
> of an implicit (inlined) one, you must specify a WindowName.

could perhaps become

"If you choose to use a WINDOW clause in a SelectExpression to specify a 
window, you must specify a WindowName to refer to it."

Otherwise I think it looks great!

> 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.
