Why is this not an element?

Why are qst and ans inline elements, forcing a complicated content
model, and restricting both to a single paragraph?

Why is there not a content model (which I would expect to look more 
or less the same as dl)?  A content model is needed, otherwise the most
important piece of information cannot be cleanly specified:  which
answer belongs to which question.

This begins to get messy, but I'd suggest that the structure here is
really:

<qa><qst>.....?</qst>
    <ans><qa><qst>Did...that?</qst>
             <ans>....</ans>
         </qa>
    </ans>

</qa>
