  <title>All Solutions that are Answers</title>
  <idx><h>solutions</h><h>all answers</h></idx>
  <introduction>
    <p>
      The back matter solutions appendix requests every <tag>answer</tag>,
      and only <tag>answer</tag>, of all types of exercises:
      inline, divisional, worksheet,
      reading questions, and projects.
      Now, as observed by Bruce Yoshiwara,
      it gets a bit tedious to see the
      <q>Answer</q>
      heading over and over in print,
      when every entry has that heading.
      So we squelch it for you in print/PDF output. (For <init>HTML</init> output we use knowls and need to have something to click on.
      But perhaps for <init>EPUB</init> we should be more careful?) Note that you might want to use a <tag>title</tag>,
      or an <tag>introduction</tag>,
      that explains which component of the exercises is being displayed,
      so there is no confusion.
