There is nothing wrong with declaring an array to have a null range
(lower bound > upper bound) and this should not raise an exception on
any validated compiler.

You will however get an exception if you try to access a null array.
Now since the dynamic string type is declared as a private type, the
package that declares the private type should have all the operations
you need to manipulate strings.  I have used dynamic strings of this
type on several different compiler implementations without error.
