Subject: Overriding the "lowest level" stream procedures

Hello.
I'd like to ensure that any piece of code in a program that executes:
T'Output (Stream, S);
S := T'Input (Stream);
(Where T is String or a type derived from String and S is an object of
any of those types)
... Has to go through my (overridden) Stream procedures. I'm
essentially trying to ensure that all textual data is written in a
strictly defined (not implementation defined) format so that the
program can communicate with other programs not written in
Ada. I also want to make it as hard as possible to, for example,
accidentally miss out a statement such as:
for X'Output use Some_Output_Procedure;
...and end up using the default stream procedures again.
I think I probably need to define my own Stream type. Is this the
case?
