Thank you for that idea.  It's one I didn't think of.

Regardless, it doesn't seem to solve the issue of binary data on storage 
devices.  Unless the descriptor was included in the storage.

I'm not sure how much of a problem this is.  For me, there isn't much, 
(but that's not none), storage of real numbers.  But for when there is, 
I don't see any easy solutions.  By now, somebody somewhere has written 
new code to look at archived binary data, and gotten erroneous data. 
Then the question becomes, do they even know they are working with bogus 
data?

No easy solutions, and I'm not sure there are even hard solutions for 
data that is already stored.
