The ARM has always tried to ensure that the language could be implemented on any 
kind of processor. Thus you have implementation-defined separate definitions of 
Storage_Element and Stream_Element, which need not be the same, and no guarantee 
that Interfaces contains declarations of Integer_8 or Unsigned_8.

But these days almost everything is byte oriented, so unless you need what 
you're writing to work on some unusual H/W, you can presume that both of these 
are bytes, and that Interfaces contains those declarations.
