That would be a big pain. I'd rather not deviate from just using 
.textContent, especially since it is what I have been using in multiple 
other places in the WHATWG specs for this kind of thing.

We _could_ special case a fallback behaviour along the lines of "if you 
don't find any numbers, then look at the IMG descendents and pick the 
first one whose alt="" text contains a number". Would that be ok?
