I would be fine, changing it to:

"Child elements should be treated like bitmap images, and should, by  
default, not be focusable."

No, it should be read as "Whatever the default behavior is, for  
bitmap images, treat scalable child elements the same. Except, there  
are specific reasons to treat them differently."

Let's try to bring this to conclusion quickly. If you think the text  
needs other changes, then please provide alternative wording.
