<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.
