Actually, the majority case will be libraries. Libraries create widget  
constructs entirely using script so the common pattern is probably not to  
use setAttribute solely to change the value.

Also, doing it like that is a hack, because the document author might have  
used another prefix, etc. Using aria-* this problem does not arise. I went  
into more detail on this in a previous e-mail I sent:
