An exercise consists of a problem and eventually its solution(s).

In a course, when it comes to an exercise, I might say "Write a program that 
outputs HELLO WORLD". There is no question/answer involved here.

But a problem may well consist of finding the answer to a given question.

Even if the exercise consists of finding the answer to a question, I do not 
directly ask the question. Instead I say "Find the answer to the following 
question" before.

Therefore <question>s and <answer>s should be allowed to appear in <problem> 
and <solution>, respectively. An <answer> should only be allowed when the 
<problem> has had a <question>. Unfortunately, this dependency is not 
context-free and therefore not expressible in a DTD.
