That which you quote means there is no way to put a qualifier on the array 
type because any attempt to do so puts it on the element type instead.  
That there are no qualified array types is simply the logical conclusion 
from there being no C syntax to write one.  Note "not the array type" in 
that paragraph.

The question of whether abstractly one might imagine a qualified array 
type in C despite the lack of syntax to describe one, and how such a type 
(notwithstanding the lack of syntax to describe it) would behave if it 
were to exist, is not an interesting one in the absence of implementation 
extensions to define such a type.
