Right. I was struggling for a term; canvas is correct.

OK. Could you explain what would happen with the other two values in 
this situation?

Rather than have the standard say it is undefined, I would rather have
it say that satisfying the request may not be possible until the 
document is fully loaded, or with partial documents.

I just have an allergy to ISO-style "this interesting bit is defined 
to be undefined" nonsense.
