The Ada 95 standard doesn't address this. The Technical Corrigendum
does, and requires that the default implementation is calls the parent
type's 'Read and 'Write. So you are not required to override. But be
sure that your compiler is implementing the TC (tests for this area have
only recently been added to the ACATS, so it is not unlikely that
compilers don't follow the TC in this area).
