A multidimensional array type can be unconstrained in all dimensions. An array 
of arrays can only be unconstrained in the 1st dimension.

type C2D is array (Positive range <>, Positive range <>) of Character;

subtype S10 is String (1 .. 10);
type SL is array (Positive range <>) of S10;

With an array of arrays, the components are arrays and may be used as such.

V : SL (1 .. 10);
...
Ada.Text_IO.Put_Line (Item => V (5) );
