Let me riff on this for second.

We *don't* know your name is David. We commonly use the identifier  
"Dave" for you, and while it's reasonable to suppose that Dave comes  
from David, we don't know that. If a metaphorical i= has Dave there,  
we can't back-translate to David, error-free.

I mention this because my father's given name is a common nickname. I  
won't bore you with the tale of his immigrant father and  
transliteration of names into the Roman character set, but you get the  
picture.

Like i=, "Dave" is an opaque identifier. One can often peer into the  
opacity and discover that it is translucent, but the process is not  
error-free, and this is why we say in DKIM that it is opaque.
