I do not believe you need to extend the root_stream_type. I believe you want
to use the 'Read for the specific data type on the stream.

For instance if you had a Header_T type defined and Hdr is an object of that
type :

  Header_T'Read ( Saveset.Savestr , Hdr ) ;

I have used this approach for heterogeneous reads from binary files.
