Even more interesting is the following:

    for access_type'storage_size use 0;

This is useful in cases where one is doing low-level programming and has
created an access type as an alternative view of another type, say
system'address. In this case one is never going to allocate any objects from
the collection for the access type, and would like not to reseverve storage
for the collection.
