I think the normal English definition applies (as it generally does 
when there is a normal English meaning and there isn't an overriding 
technical definition in the standard).  Namely...

I would say that "machine representable number" means a number that the 
machine can represent.

Note that this is definitely not the same thing as a "model number". 
The standard does define what a model number is, and it distinguishes 
model numbers from machine representable numbers.  (Which isn't to say 
that there might not be places where it gets it wrong, but the 
distinction is made).
