  <title>Solutions to a Single Exercises Division</title>
  <idx><h>solutions</h><h>for one group of exercises</h></idx>
  <introduction>
    <p>
      Sometimes you may want the solutions to exercises within a single <tag>exercises</tag> division
      (or similar, like a <tag>worksheet</tag>).
      Default behavior in this situation can produce two titles,
      when just one would be sufficient.
      Here we have used the <attr>scope</attr> attribute to point to a specific <tag>exercises</tag>,
      and provided a (single) very specific <tag>title</tag>.
