Right, I meant the cases without floats etc., such as an otherwise-unstyled
<span style="text-decoration:underline">A<span>B</span></span>
where I assume (haven't found anything explicit in the spec) that the  
first span generates a single inline box that contains A but not B's box.  
For "other elements" there's wording about an anonymous inline box, but  
not for "inline element"s (whatever that means; display:inline?).

I always read it that way too when skimming this section in the past, but  
yes, it didn't make much sense.
